Theft proof radios do, even with the radio off and the key off, the radio is still connected to the computer and seeing power, that's how it holds it's presets. When the radio loses power the computer will lock it up. When power is restored the computer knows the codes to enable the radio again. Some high-end radios lock up every time the ignition is locked, relying on the computer to unlock it.

We have owned the vehicle from new, I have no idea if the radio codes is there are any.

I had been wondering about disconnecting the battery, on a 'it's no cost and easy to try, what harm can it do' theory.

I guess the radio would be a problem.

Would pulling the fuse to that circuit be same as disconnecting the battery?

No, the radio would not be a problem. Worst case, you may lose the station presets, but you can easily reprogram them. We got off on a tangent, involving moving a radio from one car to another. Sorry if it confused you.
