Yes, it can. One reason is the structure/symbol nomenclature of runtime libraries. Another reason is entry points (names) for system calls are not prescribed by any standard, so they could be almost any name the kernel designer decides to use.
This assumes you meant for example, windoze vs unix vs xenix or something like that.
The differences between Linux Suse and Ubuntu, which I have looked at, are minimal.
One thing that can radically change the assembler code, even for the same OS and identical code, is the optimization level. Loop unrolling for example.

NAME
POE::Loop::Tk - a bridge that allows POE to be driven by Tk
SYNOPSIS
See POE::Loop.
DESCRIPTION
POE::Loop::Tk implements the interface documented in POE::Loop. Therefore it has no documentation of its own. Please see POE::Loop for
more details.
POE::Loop::Tk is one of two versions of the Tk event loop bridge. The other, POE::Loop::TkActiveState accommodates behavior differences in
ActiveState's build of Tk. Both versions share common code in POE::Loop::TkCommon. POE::Loop::Tk dynamically selects the appropriate
bridge code based on the runtime environment.
SEE ALSO
POE, POE::Loop, Tk, POE::Loop::TkCommon, POE::Loop::PerlSignals.
