Following the 'work around' instructions I was able to build a custom image. The boot menu is different between stock 20.10 and custom 20.10 (which is presumably what is dragged in from 18.04).
Since the stock 20.10 does actually boot, I think that 'they' must have changed the way the system boots of late.
Thanks for you help this weekend, my primary objective (Live-CD with absolutely latest Kernel - for changes in 'ucsi_acpi.ko' USB TypeC PowerDelivery debug) has been achieved.
