What happens if either Officer or Boarding Vader kills Tua? Will the ship lose the equipped defensive upgrade as well? It loses the icon with Tua after all. If it does, does it count in the final score as destroyed or not?

Having the retrofit slot only matters during fleet building. As such, the current ruling is that the upgrade stays.

Boarding Vader could just light sabre the ECM upgrade instead of Tua.

Asphyx-a-Vader however is free to choke Tua for the reroll and the defensive slot stays. There are other officers who's effect has already past such as Titus, Needa, Officer Ozzel and even Thrawn or Tarkin if you wait until the last command or tokens have been allocated.

“Thrawn...the last command” 👏
