Not a good idea...Unless you like fighting with funky issues....

That said in there (/var/adm/sw) you will find all the patches installed (and obsoleted, and uninstalled etc...) You may gain space by intellingently doing some cleanup, beware of the risk of not being able to "rollback" removed patches afterward... but very first superseeded patchs are of little risk...
What about /var/adm/syslog? what size are the logs there?
I trim them regularly ( customized by me though - important info in beginning syslog (at boot time) is always kept till next reboot...)

...
There are logs in /var/stm you can clean also and save 10-400 MB...
I have an old 10.20 that makes me sweat regularly (vital old legacy stuff nobody wanted to port : forms 3 with oracle 7.2.3...)
Code:
civ:/var/stm/logs/sys $ ll
total 434840
-rw-r--r--   1 root       root       220525916 Feb 24 11:29 activity_log
-rw-rw-r--   1 root       sys            878 May  5  2010 config.stm
-rw-r--r--   1 root       root          4584 Feb  2 09:02 diaglogd_activity_log
-rw-r--r--   1 root       root          5480 Feb  2 09:02 memlogd_activity_log
-rw-r--r--   1 root       root          5872 Feb  2 09:02 scan_hw_log
civ:/var/stm/logs/sys $ bdf /var
Filesystem          kbytes    used   avail %used Mounted on
/dev/vg00/lvol8     921600  555664  344185   62% /var

I only have this unique volume group vg00 in mirror on old SCSI 9GB (all space saving is important...) with all on it.
When I forget to look (thanks for reminding me Hehe...) the system crashes... and this box is not on site but in the countryside (with snow lately and Im on motorcycle...)
I just zero activity_log periodically, So Do it today:
Code:
civ:/var/stm/logs/sys $ ll
total 434840
-rw-r--r--   1 root       root       220578080 Feb 24 11:37 activity_log
-rw-rw-r--   1 root       sys            878 May  5  2010 config.stm
-rw-r--r--   1 root       root          4584 Feb  2 09:02 diaglogd_activity_log
-rw-r--r--   1 root       root          5480 Feb  2 09:02 memlogd_activity_log
-rw-r--r--   1 root       root          5872 Feb  2 09:02 scan_hw_log
civ:/var/stm/logs/sys $ >activity_log
civ:/var/stm/logs/sys $ r bdf
bdf /var
Filesystem          kbytes    used   avail %used Mounted on
/dev/vg00/lvol8     921600  338265  547997   38% /var

Look at how fast its growing though:
Code:
-rw-r--r--   1 root       root       220525916 Feb 24 11:29 activity_log
-rw-r--r--   1 root       root       220578080 Feb 24 11:37 activity_log

disktab

DISKTAB(5)						      BSD File Formats Manual							DISKTAB(5)

NAME

     disktab -- disk description file

SYNOPSIS

     #include <disktab.h>

DESCRIPTION

     disktab is a simple database which describes disk geometries and disk partition characteristics.  It is used to initialize the disk label on
     the disk.	The format is patterned after the termcap(5) terminal data base.  Entries in disktab consist of a number of `:' separated fields.
     The first entry for each disk gives the names which are known for the disk, separated by `|' characters.  The last name given should be a
     long name fully identifying the disk.

     The following list indicates the normal values stored for each disk entry.

     Name      Type	Description
     ty        str	Type of disk (e.g. removable, winchester)
