Can Drywall be installed over plywood?

Yes, it certainly is possible, but not very practical due to the additional material and labor to install. You would probably use 1/2″ Plywood which is much more expensive than 1/2″ drywall. Even if you used 1/4″ Plywood, the cost of that for an entire room or house would be substantial.

How do I make OSB look smooth?

Acrylic latex stain-blocking primer will hide any stains on the OSB. This also seals the paint and prevents any bleed-through.
