Not a lot that I can see.
There's quite a lot of Egyptian-influenced naming (though ancient rather than modern) for systems and I think also stations.
As for the rest of the continent, nothing obvious - none of your examples match anything. Thinking about how station and system names have been chosen, there are very few named after cities, nations or political figures [1] - scientists, astronauts or scifi authors are more common, and might be an easier place to start looking.
(Someone had a project to list who each "X Hub" station might be named after, but I can't remember who or where...)
There are procedural system names which sound "generic African" in the same way that some of them sound "generic Asian" or "generic European", but that's asking for a couple of transliterated syllables to do a lot of work and they're probably mostly no closer to actual words than somewhere like "Langloines" is to being a believable English word.
[1] The exceptions - e.g. the stations around Earth, or "Birminghamworld", or indeed "New Africa" - I think are all ones inherited from the FE2/FFE non-procedural names, which were perhaps chosen to very different requirements.
Edit: For Nobel Prize winners, there are stations named:
...Zewail, probably after Ahmed Hussain Zewail, Egyptian, Chemistry
...Lessing, maybe after Doris Lessing, Zimbabwean, Literature
...Cormack, maybe after Alan Cormack, South African, Medicine
...and a single Camus Orbiter probably named after Albert Camus, Algerian, Literature
