Yes -- they will let you boot into the system. The rescue initrd includes
all available drivers and so can boot even if the drive is in a very
different system from the one it was installed on.
Are there automated or manual procedures to update
a rescue kernel?
There's generally no reason to. But you can with
/etc/kernel/postinst.d/51-dracut-rescue-postinst.sh $(uname -r) /boot/vmlinuz-$(uname -r)
Are there best practices for rescue kernel update?
If there are, I've missed them.
That's because the best practice is generally to not worry about it.
