In a previous round up you mentioned that if Ion Blaster of
Optimus Prime was played on Optimus, then he was combined into
Optimus Maximus, the Combiner could keep that weapon, however not if he was already formed. I’m assuming that also works with
Laser Cutlass? Play onto an Aerialbot for example. Once combined, does it carry over?

Yes.
Can I play Ion Blaster of Optimus Prime on General Optimus Prime? Ion Blaster says "Play on Optimus Prime only", so would the word "General" in his name disallow it?

Just because he's a General doesn't mean he's any less Prime! You may indeed play Ion Blaster on General Prime.
