Since we are talking about uses and sources for charcoal, and not about using it in anything that's prohibited on the forum...,
I've found that when hardening a frizzen, the "cowboy lump charcoal" on a forge works well for fuel..., though I have no idea the wood source for that charcoal and would only try it in other situations calling for charcoal as an experiment. IF the stuff did work for other applications, the problem would be one would not know when or if the charcoal maker changed or mixed wood sources.
Now, for something like blackball...
If one is looking to make a period correct shoe dressing, aka blackball, it's roughly 35% beeswax, 40% tallow, and 25% carbon of some sort. The highest quality stuff was made using bone black, not wood charcoal, but well powdered charcoal should work well enough for a common man's shoes. Helps with water resistance too.
