Yes but if they were connected to the same router. Most of these systems are distributed and having multiple APs connected to some central Radius server. Because modern systems optimize for roaming between nodes, you can join network, use dns-sd to gather mac addresses of the computers which are not physically connected to your AP (in conjuction with 'tcpdump -I') Then voila, 2 devices using same MAC without any problems. PS. I personally use "printer" addresses for 2 reasons: 1: generally everyone forgets to nicely setup firewall for them since they're infrastructure objects. 2: they have relatively less traffic and probably located some obsecure room with an AP for them.
