No, the tube helps hold the tire on the rim. Without a tube the tire is more likely to blow off the rim. I think Stans rims have a max pressure of 55psi for mountainbike tires. Their CX rims have a max pressure of only 45psi.
Plus running high pressures sort of defeats the purpose of going tubeless, but to each their own.
