I had a brief look at the network manager source code that is in the Ubuntu repositories. While I am no developer, I do see that there are numerous references to VLAN in the code.
I also see that concerning the plugins only the rhel parser has vlan references, not the ifupdown.
My current take is thus that network manager does have VLAN support in Ubuntu (if it hasn't been disabled somewhere), but you cannot use the /etc/network/interfaces file for these. The "keyfiles" in /etc/NetworkManager/system-connections/, however, could well be usable, if someone finds out, how to configure a vlan there...
