Unlikely.
Once Freddy gets to Norsca, he will be going through the land route from somewhere on Norsca's northern coast, travelling overland through a cold frozen deathland that serves as a border between Norsca and Kislev, then into Kislev. This will take months, as the current travelling group are optimistically, Jacque's girls, Jacque, Roland, Eldyra, Hultressa, Gwendolyn, Natasha, Freddy, The Handmaiden of the everqueen, the Asrai, and any survivors from the slave revolt we intend to use as a disraction, plus Maghda, and Johanna. That's 11 to maybe 50, or a few hundred people we will be tavelling with into Norsca then to Kislev with. Without prior preperation for the environment.
Even if Freddy could be tracked, he cannot be picked up by the Barak Varr remnants any time soon after leaving the Black Ark he is currently on, then eventually no sea access until Kislev.
