I just installed a new kernel using this command dnf install kernel but on reboot the old kernel still comes up!

Currently, in Fedora the package kernel is just a meta-package containing information about a specific version of the kernel. You can see this by running dnf list installed kernel and dnf list installed kernel* and seeing how many more packages the second command lists. The easiest way to do what you want is to run dnf upgrade kernel* because that will give you the latest version of all the needed files and update GRUB to show the newest version.

The kernel packages requires kernel-core and kernel-modules, so installing kernel will cause the other two to be installed as well.

If you already have a kernel installed, running dnf install kernel would not do anything. It it tells you so.
