If the ground is slippery (snow or rain, or anything else) then I wouldn't risk jumping in it... where common sense plays a role.
However, if you're riding in good footing that doesn't slip and slide, then why not? There are races run in the snow, as long as you're smart about it, then there's nothing wrong with it.
Conditions permitting, there is no more risk in jumping in snow than there is in rain.
Just use your head.
