Sure, provided everyone agrees there have been no transactions and what the end result was. The PoW is necessary to ensure this consensus, but it would indeed become obsolete if people found a different way to form a consensus of the final state (ending bitcoin).
Do you have to do proof of work when there are no transactions?
My understanding was that the PoW was done to place transactions on the block chain. If nothing has changed, nothing has to be done. The entire system can be offline and archived if we have 0 transactions.
