Yes, it can.  For years gcc based cross-compilers for Atari ST
are running on different platforms.  Configuring gcc for a cross-compilation
is directly supported in gcc sources.

You need a special linker which will produce Amiga binaries.

Likely.  This depends on your (cross)linker.  It may be happier with
another format.  If you have library sources and a cross-compiler
than this is not a big problem.  You just have to recompile libraries.
The only point is that your compiler and linker have to agree what
an intermediate format is.  Once you decided on that you need also
a bunch of auxiliary tools (librarian, stripper, symbol table lister,
things like that - i.e. ar, strip, nm, ... for a cross-compiler).

In summary: this is a fair amount of work if you are doing that from
scratch but this is definitely possible.  Bits are bits and a compiler
is just producing a pile of them.  It is only OS and its loader which
later tries to make some sense of that. :-)
