Does the present Archbishop of Canterbury enjoy the jurisdiction granted to his pre-reformation predecessors by the Pope, or is he linked with them only by orders

He has no link with them either by jurisdiction or by Holy Orders. He merely retains the name without the reality, and owes his position to the crown. All the privileges once granted to the Archbishops of Canterbury by Rome are now granted to the Cardinal Archbishop of Westminster. If the present Archbishop of Canterbury were converted to the Catholic Church, and wished to exercise priestly functions in that Church, he would have to be ordained as if he had never claimed to be a cleric of any description previously.
