Yes.  An interrupt will occur if the current status of the pins is not
equal to the status the pins where in during the last read operation.

If you mean that you have an _external_ signal (being a one) _and_ the
int-pin set to output, than the answer is Yes.  If the 'one' on the int-pin
is an effect of a output (from the PIC itself) to that pin, than the answer
is No.
