I would not remove it as there will almost certainly be a mark or damage left behind.
Commercial mounts like the one shown above are available everywhere, so follow the mounting instructions and check it can carry the weight of your TV and you should be good to go although I would remove the TV from the mount when travelling.
I agree with Raywood. Don’t remove it. The board it is attached to probably won’t take the weight of the bracket on its own and the dedicated plate is for strengthening. Also always remove the TV from the bracket when towing.
