It's been 120 years since the Burn, the only Klingons that would still be refugee's are one's too stubborn to settle down for one reason or another.Yes, maybe so? But Klingons being refugees appears to be a more general thing than just this one group. I think. It seems to be that this particular group are the remnants of Klingon governance and the ones who would need to take the lead in settling a new planet.
Also, there's probably still that planet full of Klingons in the Delta Quadrant.
