Curiosity killed the cat: is it possible to get a valid cert for IPs on private LANs, like for example 192.168.1.42 or 10.0.0.84?

No. The certificates are for a claim that this is your IP, but it's not your IP, it isn't anybody's IP.

Same way you can't get a cert for some.name.in-an-internal-domain-we-use-internally

Sure you can, you just have to issue it yourself.
