I Hit My Approach Shot Onto The Wrong Green And Then Played It As it Lied. Was That Correct?

Can you play from a wrong green?.

You’ve played a solid drive up the middle of the 10^th fairway and have an enticing 150-yard approach into the green. You’re feeling confident.

You make a steady backswing but then get too eager in the transition, you come over the top and pull the shot. As such, the ball goes long and left, it kicks on further and comes to rest on the 12^th green, 20 yards beyond your target putting surface.
