Black and white stabilizers (are there still any? I only knew Agfa Sistan, which is gone) were essentially antioxidants, while colour stabilizers are fixatives that immobilize the dye molecules in the gelatin. So no, they are not interchangeable - black and white film does not have dye bleed issues, the silver being a inherently immobile pigment.
Most (perhaps all) colour stabilizers come as a Stab+Flo mix for the final rinse and contain the same surfactants as commercial Photoflo preparations - so these can be used as a flo substitute. However they will have no stabilizing action on the silver, but rather the same effect on the gelatin as a hardening bath. That may be desirable on ancient soft films (like Efke), but on modern, prehardened film it will cause increased curl, so I would recommend regular wetting agents for general use.
As far as the Tetenal kit goes, its stab does bubble, which I'd consider a indication of a stab+flo mix, in spite of that APUG post.
