not so sure.
it's usually possible to include in any file dummy code (at the end,
by example), never executed, but this allow to adjust a file.
it's also possible to delete some part of the code, most application
have very rarely used code one can delete without notice
so, in theory, it's possible to change an application working and
adapt to have the same md5sum.
but I nevre heard of such thing so this may be very difficult to acheive.
if it's not possible to have a calculation of the missing code (ie
md5sum1 - md5sum2 gives the code to add), finding the necessary code
may be impossible
