I'm not sure I understand the question completely, but if you're asking
if you can transport MPLS in a VLAN in a trunk, the answer is yes. MPLS
runs just fine, although you have to consider the overhead from the
802.1Q tags (4 bytes).

If it's a wise thing to do is another matter. Why would you want to?
