I want to move radiators without removing them, and without draining,

I believe rads are usually hooked onto brackets on the wall, in which
case how does one move the thing without unplumbing it? Theyre modern
rads, probably early 70s.

I know this is done, just dont know how to do it!

The bracket 'hooks' are usually 6-10mm deep, so you only need to be able
to lift the rad by that much. If the pipes go through the floor, there
is almost always enough play to unhook the rad.
