I didn't try to study the entire datasheet for it, but first, I'd
simply assume that works.  Why not?  After all, external interrupts in
other chips could also always be triggered if the respective pin was
configured as an output, and this is a documented feature.

Second, why not simply put an ATmega88 into an STK500, and just try
it?
