yup sure can!
either you can chose to desginate a new vlan for that session, or if you want to run it inband you can do that also with a bvi:
int g0/0/0/0.100
encap dot1q 100
ipv4 add....
router bgp
neig... etc
or if you have an existing circuit, say g 0/0/0/0 l2trans
then confgure
int bvi 999
ip add...
l2vpn
bridge-group X
bridge-domain Y
int g 0/0/0/0
routed interface bvi999
