Yes.

Not really advisable if you are wanting to return back to AmigaDOS afterwards though.

And how should that be possible, loading the exe to $30000 in c-mon and jump to $30028 (program start) results in guru....

If the code is 100% pc-relative you can simply copy it to the destination address. If it isn't however that will not work, you have to relocate all RELOC32 entries to the new destination address (parse the RELOC32 hunk and adapt the code in the binary).

A simple and easy way to do all this: just crunch the binary using a cruncher that supports absolute addresses (CrunchMania, StoneCracker etc.) and simply let the cruncher do all the work for you.

Or, if you want to make some test and mod before the crunch, use this:
