Let me comment on my own message:
I believe I forgot to scrutinize the file /etc/default/grub.
This file is 'automagically' created when fedora (grub2 ?) is installed the
very first time, and its contents is based on the boot conditions at that time.
When changing the boot conditions later, those changes are NOT 'automagically'
progressed into a new /etc/default/grub. I guess this has to be done manually.
The "grub2-mkconfig -o /boot/grub2/grub.cfg" uses the settings in
/etc/default/grub to create the grub.cfg file. Hence, without changing the
default grub file, the old boot conditions still appear in the
/boot/grub2/grub.cfg file.
I found many manual on the web about "how to make a new grub2 boot loader", but
none mention to scrutinize the default grub file for old configuration
settings.....
(I currently have no access to the troublesome PC, so I will try this later).

Thanks Chris Murphy for your feedback.
In fact, I do believe my basic idea was OK, of copying the system files from
one disk on the logical volumes to another disk with regular partitions. I
could do this safely while booted from a Live USB medium.
It turned out that /etc/default/grub was the culprit that stopped the boot
process. This file contains the boot conditions as configured during that first
install. The file is 'automagically' created by anaconda during the first full
install of the OS. There is a python script in the anaconda package that is
responsible for this, but it is (for me) unusable as a stand-alone module.
I you are changing the boot conditions later, then that file needs to be
adjusted manually. Unfortunately there is very little information around about
what changes should go in there for a given boot sequence......
Fortunately I have another fedora PC that boots from regular partitions and I
copied the /etc/default/grub from that PC. After that I created a new
/boot/grub2/grub.cfg and recreated the initramfs with dracut (I'm not sure the
latter is really necessary).
Then the PC booted flawlessly.
I figured that /etc/default/grub is still a rather undocumented 'feature' of
the new grub2 bootloader.....
