I.e. does grub insist on its configuration/files being in a directory
called /boot?

No, but Ubuntu, like many distributions, puts kernel files and grub.cfg in /boot and grub-mkconfig looks for kernel files there.

Further to this I suppose I can create a small new partition on the
'relatively fast' SATA SSD in which I create the /boot for the new
19.10 installation on /dev/nvme0n1p2.  This wouldn't be an issue.

So, I *think* the resulting configuration would be:-

     /dev/sda - unused, spare spinning disk

     /dev/sdb
         /dev/sdb1 - Linux partition with /boot and the rest of 19.04 
installation
         /dev/sdb2 - Small partition with /boot for 19.10 whose files are on 
/dev/nvme0n1p2

     /dev/sdc
         /dev/sdc1 - /home

     /dev/nvme0n1
         /dev/nvme0n1p1 - swap
         /dev/nvme0n1p2 - 19.10 installation (but no /boot)

... but I still don't quite know how to tell 
grub-mkconfig/grub-install/update-grub
how to make things like this.

In Ubuntu 19.10, just mount /dev/sdb2 on /boot.
