If you install the dnf-plugins-core package, there is a plugin
dnf.plugin.protected_packages.  If you do a man on that, 
man 8 dnf.plugin.protected_packages
it tells you to put the package you want protected in 
/etc/dnf/protected.d

I would put the kernel package you want to protect in there, and then
try removing it with dnf. See if it tells you that it is protected.
If it doesn't, don't press Y.  :-)  The man page also says that the
currently running kernel is protected, but I have seen elsewhere that
dnf does *not* protect the currently running kernel, and that this is
per design.

If worst comes to worst, and you need to install an older kernel
package, go to koji and download an rpm you know works, and force
install it.
