Don't think they are billed as tubeless(or 2-way fit in Campag/Fulcrum speak) but seems that some people have run them tubeless.
Spoke to a Schwalbe UK guy a couple of years ago and he was riding Schwalbe Pro-ones on standard Shamals.
Obviously no comeback from Campagnolo/Fulcrum or whoever's tyres you are using if anything goes wrong.
Oh and I'm running my non-tubeless H+Son Archetypes tubeless with no issues.
