Ive seen a lot of tandems with 40 spoke wheels. Be sure you get some strong enough. Also most of them ive seen have hub brakes, to assist in slowing the bike down big hills without the rim getting overheated like with ordinary calipers.
Im no tandem expert though, id just be very careful of the choice. Remember they are getting put through double the stress.
