Well, I don't think so. See below for a quick experiment:
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
[EMAIL PROTECTED] tmp]$ mkdir try
[EMAIL PROTECTED] tmp]$ cd try
[EMAIL PROTECTED] try]$ touch foo
[EMAIL PROTECTED] try]$ ls -l
total 0
-rw-rw-r-- 1 cdl cdl 0 Aug 23 08:48 foo
[EMAIL PROTECTED] try]$ ln foo bar
[EMAIL PROTECTED] try]$ ls -l
total 0
-rw-rw-r-- 2 cdl cdl 0 Aug 23 08:48 bar
-rw-rw-r-- 2 cdl cdl 0 Aug 23 08:48 foo
[EMAIL PROTECTED] try]$ chmod o+w bar
[EMAIL PROTECTED] try]$ ls -l

Note that there is only one set of mode bits, and the file has the
same modes regardless of what you call it.
