If you 'accidentally' move your ball on the fairway and replace it without penalty you may improve your lie. On the tee you can shift it around anywhere you want and on the green lies barely change.. Accidentally moving the ball on the tee doesn't count, but accidentally moving your ball on the fairway without even touching it does count. Seems bizarrely inconsistent to me. Should be able to replace it free of penalty either way.
