From what I've seen.
Rescue kernel is two files.
On my machine these are the current names.

Removing them, and doing dnf reinstall kernel-core will create new
ones.
Thank-you, Mike.
On to the real question...
I know a few people have encountered running out of storage space when a
kernel gets patched or upgraded. It happened to me a few times. I
recall seeing somewhere that this can be avoided with wise partitioning,
which is a part of installation. I also recall seeing that kernels have
grown quite a lot over the years. (Hmmm... Is someone feeding them
too much fructose and other "refined carbs"?)
I recently had this issue with machines with nvidia cards. The img
files where create with about 100M larger files then similar
machines without nvidia card. So with 3 regular kernels and a
rescue kernel it was requiring about 400M more space.
My quick solution to get around that was to manually remove the
oldest kernel and modify the /etc/dnf/dnf.conf file
changing line
installonly_limit=3
to
installonly_limit=2
Then install had enough space.
Later booted from live Fedora 42 on flash, installed gparted.
Changed / partition to have 512M space before
Then enlarged /boot to add that extra space maching /boot 1.5G
Again, would depend on your setup, I have regular ext partitions
Just an issue if machine locks or poweroutage. Did a disk image
back before, and had battery in notebook fully charged, and a UPS.
So now /boot has enough space even with larger kernels.
I've done that too, at least twice, very probably at least 3 times.
Kernel growth was at least a major factor, but maybe not the only factor.
