I want to remove a radiator so that I can strip and replace the wall

drain the system :-(

You need a decorator's cap for the TRV: you should have had one for each
valve when they were installed, but if not you can sometimes get away with
putting something like a coin between the head and the valve so that you
can turn it off completely.

You can also use a G-clamp, with a bit of care...
