[X-Newbies] Changing Names of Applications

[Al Poulin]

Hello listers:

I understand that renaming things in OS X can sometimes bring disaster. 
  I am using Panther 10.3.7.

I have installed two Harry Potter games with very similar names.  The 
distinguishing parts like "...and the Sorcerer's Stone" and "...and the 
Chamber of Secrets" are missing.  Both games are in the Applications 
folder.

Can I add the words "Stone" and "Secrets" to the names without buying 
into problems down the line?

Thanks,

Al Poulin
