If the oil level is too high the surface can be frothed by vortices generated by the rotating crankshaft (known as windage). This can result in an oil/air mixture being pumped around the engine; i.e., reduced lubrication.
Worst case scenario, if the level was sufficiently high, it could be contacted by a descending piston under heavy braking or acceleration, resulting in substantial engine damage.
