The deep square rim sounds like it would be tubeless (the rim band sits inside and seals the square part) but i didn't think the front was tubeless just the back - could be wrong
My 03 250 txt has a normal rim, tube and rimlock on the front so no reason why you cant change the front (I even ran the rear with a tube for a while without issues - actually less issues since the tubeless system actually looses air over time)
could also try asking on one of the trials forums
