No. W is a revenue class within Europe and NOT available for awards, and an award booking class for elites on long-haul flights. Same as A class (discounted economy within Europe, and first class award inventory on long-haul flights).

On an award, the segments within Europe are all booked in X class. Only the long-haul goes into W class.
