Looks like typical Peltiers are rated for a minimum temperature of -40 to -50 C, so they can definitely go well below freezing. And I would assume you can find ones that are specifically intended for cooling and are rated for lower than that.
One problem is that the efficiency of a Peltier drops at low temperatures - and they're really not all that efficient even at room temperature. So you wind up having to dissipate lots more waste heat on the hot side than you're sucking out of the cold side.
