No you cant...
Only way I see ( and do sometimes...) is to create a directory called serverB in the filesystem present on that logical volume and use that as source to be mounted then on serverB it will show up as empty mount point...
The issue I see is you cannot avoid serverA to see the content and it is wise someway for the safest way to save the data stored here would be by serverA backups...
You can try to limit access by changing permissions on this directory and change owner and group to someone known both sides

MOUNT_HFS(8)						    BSD System Manager's Manual 					      MOUNT_HFS(8)

NAME
mount_hfs -- mount an HFS/HFS+ file system SYNOPSIS
mount_hfs [-e encoding] [-u user] [-g group] [-m mask] [-o options] [-j] [-w] [-x] special directory DESCRIPTION
The mount_hfs command attaches the HFS file system residing on the device special to the global file system namespace at the location indi- cated by directory. This command is normally executed by mount(8) at boot time. The options are as follows: -e encoding (standard HFS volumes only) Specify the Macintosh encoding. The following encodings are supported: Arabic, ChineseSimp, ChineseTrad, Croatian, Cyrillic, Greek, Hebrew, Icelandic, Japanese, Korean, Roman (default), Romanian, Thai, Turkish -u user Set the owner of the files in the file system to user. The default owner is the owner of the directory on which the file system is being mounted. The user may be a user-name, or a numeric value. -g group Set the group of the files in the file system to group. The default group is the group of the directory on which the file system is being mounted. The group may be a group-name, or a numeric value. -m mask Specify the maximum file permissions for files in the file system. (For example, a mask of 755 specifies that, by default, the owner should have read, write, and execute permissions for files, but others should only have read and execute permissions. See chmod(1) for more information about octal file modes.) Only the nine low-order bits of mask are used. The default mask is taken from the directory on which the file system is being mounted. -o Options are specified with a -o flag followed by a comma separated string of options. See the mount(8) man page for possible options and their meanings. -j Ignore the journal for this mount. -w Mount the HFS wrapper volume. -x Disable execute permissions on a standard HFS file system. SEE ALSO
mount(2), unmount(2), fstab(5), mount(8) BUGS
Some HFS file systems with highly fragmented catalog files may not mount. HISTORY
The mount_hfs utility first appeared in Mac OS X Server 1.0. Mac OS X March 14, 2001 Mac OS X
