Collective - no
Pedal - I would be v. careful. Living in N Europe, very easy to get into a routine which - in icy conditions - you may apply without thought and end up frightening yourself / others (or worse).
I would not go there. Particularly as a low-hour pilot.
If you are talking about the helicopters yawing on the ground (Or on the water with floats etc) with application of the collective then I would say I do not think so. The engine (I am assuming here) is off therefore there is no torque. That being said if you were using a rotor brake the helicopter will tend to turn in the direction of blade rotation upon brake application.
