As everyone else has said, feed him in his enclosure. There is absolutely no need to move him. He will not become cage aggressive, he won't mistake you for food, and he won't turn mean. Those are myths. Be safe - feed him in his cage - and relax.
Believe me, when he's full grown, there is no way on this Earth that you are going to want to MOVE a 7-8 foot boa constrictor in full feeding mode.
