This is not legal. The Centaur must have sufficient transport capacity
currently available to hold the crew, even though they don't actually embark. You declare the tow, move the Centaur up to 12", and then place the gun and crew as if they had just disembarked. If the command squad is in the Centaur then it doesn't have enough transport capacity for the crew and you can't tow the gun.
