Yep, no problem.  Just remember that with a standalone pure assembly
program you need to fill certain things in that you don't need to
worry about when using C or BASIC or other high level language.  For
example, the interrupt vector table.  You gotta do this by hand.

AVRDUDE doesn't care - it just downloads the given data to specified
memory.  It has no way of knowing whether you are downloading a valid
program or not.  In fact, when testing changes to AVRDUDE, I
frequently download ASCII byte patterns into flash and then use
terminal mode to dump sections of memory to make sure everything got
put where it should.
