Yes but you are talking about
crossing fronts with sfc temp below zero, which is a different magnitude of risk altogether.
I would never do that and I rarely go anywhere near fronts (except fly straight over the top, enroute, up to FL200 if necessary) even in the summer.
Once, flying with an instructor "who knew everything" (but it turned out had never been anywhere) I was collecting ice rapidly at FL090 over Germany, in August. We had to descend rapidly from FL120 to 080. Best to not play with frontal wx at all, unless you have de-ice and radar
Another risk in departing with sfc temp below zero is that any delay in collecting the IFR clearance from London Control is going to put one in hazardous wx, for an indefinite period. So a departure from an unmanned airfield, or one which can't/won't call up LC for the initial clearance, is a no-no if the cloudbase is low.
