Due to the relatively low pressure involved with MTB tyres, pretty much any tyre can be made to work tubeless, you'll just need a bit more sealant to allow for more than normal soaking into the tyre. Often, but not always, non-tubeless tyres can be a looser fit on the rim (depends a lot on both the tyre and rim size tolerance), which can make them a bit more difficult to pop into the beads before the air falls out. If you have time to play with, fit the tyres with tubes & let sit for a couple of days to iron out packaging kinks, then go tubeless with them.
