Other than the perchlorate problem (which is a real problem, but they can be baked out with heat as I understand it) I don't think we know any reason why not.
You'd have to fertilize the soil of course, but fundamentally plants don't need that much to grow. A lot of hydroponics use a completely inert "gravel" like substance and just wash a nutrient solution through on occasion.
