http://www.microsoft.com/mscorp/ip/tech/fat.asp

lists four patents regarding FAT (plus unspecified further ones). Do all these cover file name encoding?

Yes, patents may be overturned. But the amount of legal FUD that can be launched with all this is potentially huge. And, some patents may actually be enforceable.

Anyway, I was curious whether the actual patents cover the implementation in the Linux kernel. Is that so?

I just looked up all four on the USPTO site. The earliest of them is dated Nov 26, 1996 (filed April 4, 1995) and, based on the summaries, they all relate to maintaining both long and short filenames in the filesystem.
