Yes.  Any pathname, absolute or relative, is possible.

This should not in any way complicate your program.  All you need to do
is (try to) open the given file.  Passing a relative or an absolute
pathname to open(2), for example, makes no difference, and open(2) would
do the right thing.

Or is there a scenario where using either an absolute or a relative path
would make things more complicated that I'm not considering?
