I will look into it. Although what I found out at first did not look that much promising.
Will this mean that I have to replace grub by extlinux?
When I say "this use case" I'm not recommending it for you necessarily.
I'm saying for those who insist on having bootloaders installed to partitions/volumes
rather than using GRUB the way it's intended to work, should use extlinux which is
designed expressly to work by being installed to each partition's VBR.
I would just use the Fedora installation of GRUB, let it step on Ubuntu's installation
of GRUB (which still keeps the Ubuntu grub.cfg intact), and then edit Fedora's
/etc/grub.d/40_custom file to add an Ubuntu configuration entry that uses configfile
pointing to Ubuntu's grub.cfg. That way anytime you run grub2-mkconfig on Fedora, the
resulting grub.cfg always has an entry that points to Ubuntu (as well as Fedora entries).
And Ubuntu kernel updates will be reflected in its grub.cfg.
