One side-effect of this rule would be that "IBM" would be wiped out from a line like this -

Code:
-Z123IBM -Z12X Corporation

I hope this is what you want.

The modified script is as follows:

Code:
perl -lne 's/^Z{2,}| Z{2,}$|-Z\d+.*?\b|-Z(?=\b)//g; print' your_file

Test run:

Code:
$ 
$ cat -n f4
     1  HHS/CDC
     2  55304
     3  ZZZIBM Corporation
     4  ZZZIBM Corporation ZZZZZ

     6  IBM ZZZ Corporation ZZ
