IIRC there's some strong hints (maybe even a WoJ?) that there's an Alera / CinderSpires link, but less so for something as close to our "Modern World" as the Dresden'verse is.
But of course nothing's impossible, and WoJ says the Nevernever is virtually-limitless, and explicitly includes all sorts of fiction & fantasy places, e.g. Spiderman lives somewhere in the Nevernever, and Frodo in some NeveneverShire, &c.
