Principally, yes.

But are you really sure that it is the updated kernel package and not
your grub installation or config which causes your boot failures?

Your description sounds pretty weird to me. Above all, what is a grub
legacy partition and why do you need chainload in grub legacy for
booting a Linux kernel? And are you sure that grub legacy is the right
bootloader for your uefi mainboard?
