Apart from the obvious answer that it'd take too long to get the booster back across the Atlantic, why doesn't SpaceX leave the main or centre booster in space a little bit longer and guide it to land on dry land rather than on a small pitching barge in the middle of the ocean?
It wouldn't help in cases where there's damage to the booster, but I would have thought that it was an easier target.
Would the booster be traveling too fast to slow down safely?

The boosters do not have the range to get to Africa because they aren't going fast enough. If you look at the graphic below it shows a Falcon Heavy mission. The side boosters do not get very far downrange at all so they return to the cape. The drone ship for the core booster was located 1236km downrange, Africa is over 6000km downrange.
The graphic came from this site, which has many other profiles.

We saw with the Falcon Heavy third flight (STP-2 mission) that the center core landing was attempted at 1240KM from launch, which is the farthest recovery attempt to date.
A consequence of the farther distance is that the speed of the core at separation is higher, which requires more fuel to slow down for the re-entry burn.
It appears they did not allocate sufficient fuel in the re-entry burn to slow down enough to survive.
This provides an excellent data point for SpaceX.
Thus to land in Africa means it would likely be moving much faster, and thus require more fuel to slow down to survive contact with the atmosphere.
The trade offs may not work out, compared to a landing closer to the launch site.

The center core failed to land because of a mechanical fault with the center engine's vectoring system. It had enough fuel.

Aside from the technical aspects, Africa is comprised of a couple of dozen different countries, all with their own rules and politics, but none of which would appreciate a botched booster landing in their urban centers. Even one incident like this would be enough to make sure no more flights happen.
