No, you cannot put two wires under one screw on a neutral or ground busbar. Terminal screws are designed for one conductor unless specifically rated and marked for multiple wires. Doubling up can create loose connections. This causes overheating and is a fire hazard. If you need more connection points, a licensed electrician can add an approved accessory ground or neutral bar to your panel.
