No it would be against the conditions of their security pact, it's meant to be purely defensive:
Shilao and co did point out a while ago when the Pakistan involvement first came to light that this is indeed going to be a sensitive matter since it involves Chinese hardware. He said the fact that Pakistan's contingent in Saudi Arabia doesn't include J-10CE means Pakistan side have also thought about this carefully and made the right call. If there is J-10CE based in Saudi Arabia should Iran consider hitting them with Shahed or not? Even if Iran doesn't try to target them, you can never tell if US wouldn't try to hit them with LUCAS drone and pretend it was Iran to stir up drama.
