Does the Dominion of Draka count?

Seriously though, I think it might just be possible if you leave it late enough. With a subtle POD, things progress pretty much as IOTL until the Cold War era- except that tensions reach breaking point, the Cold War goes Hot, and we see a full-blown nuclear exchange between NATO and the Warsaw Pact. MAD ensures that the eventual winner (probably NATO, but depending on what the POD is, you never know) comes away with a pyrrhic victory, and the vast majority of Europe's population, along with virtually the entirety of its administrative base, is annihilated over the course of the conflict. As by far the least relevant continent in the Cold War power struggles and during the conflict itself, Africa emerges practically unscathed from the nuclear destruction wrought by WW3, with the African nations' power relative to the ROTW vastly increased.
And if WW3 breaks out early enough, before several African nations gain their independence and break away from colonial rule, you'd almost certainly see a few instances where the roles are reversed in the aftermath of WW3; with colonial nations such as Portugal, Belgium, Spain, France and potentially even Great Britain moving their capitals and political administrations to Africa, but retaining their territorial claims to the tattered war-torn remnants of their homelands in Europe by administering them as colonies, with expatriate communities from less desolated regions of the world offered incentives to return as colonists and repopulate the area. It's a pretty bleak way to go about it, definitely more of a ROTW-screw than an Africa-wank, but IOTL that's how any realistic simulation of a nuclear exchange between the two superpower blocs in the Cold War would have inevitably panned out, and it's the most realistic way- perhaps the only realistic way- in which an African nation could establish a colonial foothold in Europe with a POD post-1700.
