They can mate but they will not get pregnant.
I have seen neutered dogs hump and tie spayed female dogs..
However
it could be fatal to the female dog if the vet performed a "Tuck" as they call it..
SOME vets remove the vagina just passed the urethral opening.
A male dog has a very real bone made of cartilage within his penis.
This bone can easily rip the tuck open and since there is no vagina this could open her exposing internal organs and leaving her to bleed to death if not treated
