If anything I’d think Palpatine would be pissed that Tarkin didn’t survive to be tortured to death by him. He was in charge of the cool new toy and it got blown up!
I think that's one of the reasons Tarkin didn't even entertain the thought of having an escape plan. It wasn't just arrogance. He knew if things went wrong he'd be far better off going down with the ship.
