We ran into this problem when trying to remove Xenix from a hard disk.
It turns out the way to remove a Xenix partition is to boot Xenix from
floppy and use the Xenix fdisk program.  If you boot from the hard disk,
fdisk fails because you're trying to remove a partition that has a
mounted file system on it!

It's been a year or so since I had anything to do with Xenix, but this
information is probably still valid.  At least, it's another avenue to
explore.
