They'll probably be able to get it minimally working, but much of modern weapons tech is in the software, targeting systems, precision firing timing, etc. It's possible these tanks are too old for that to be a factor though. It is theoretically possible to lock down the system to only authorized users, much like what we see with TPMs and modern smartphone security. This is supposed to be part of the reason the F35 program was so expensive - every component is cryptographically signed and verified.
