I've installed fedora 24 and updated kernel.
$rpm -qa kernel
kernel-4.6.4-301.fc24.x86_64
kernel-4.5.5-300.fc24.x86_64
So kernel-4.6.4-301.fc24.x86_64 is installed.
$uname -r
4.5.5-300.fc24.x86_64
Current loaded kernel.
$ cd /boot
$ ll
total 90117
...
-rwxr-xr-x. 1 root root 6277656 Jul 29 07:09 vmlinuz-0-rescue-60cb3109c1ea41d6806444bff16cc074
-rwxr-xr-x. 1 root root 6277656 May 19 16:21 vmlinuz-4.5.5-300.fc24.x86_64
But there is no file for 4.6.4 kernel.
How is it possible to add newer kernel by hand into grub?

edit grub.conf file if you are using Redhat/ Centos
Copy and edit the old kernel parameter and replace
old parameters and locations with newer one

It's high time that you do
For BIOS
cp /boot/grub2/grub.cfg /boot/grub2/grub.cfg.bak # Creating a backup of current
grub2-mkconfig -o /boot/grub2/grub.cfg
For UEFI
Under EFI, GRUB 2 looks for its configuration in /boot/efi/EFI/fedora/grub.cfg
cp /boot/efi/EFI/fedora/grub.cfg /boot/efi/EFI/fedora/grub.cfg.bak
grub2-mkconfig /boot/efi/EFI/fedora/grub.cfg
Note
if you get
grub2-mkconfig : command not found
that means, you haven't installed the packages that provide these tools (very rare though!), then you need to install them first
dnf install grub2-efi grub2-efi-modules shim

I had the same problem with a clean install of F24, using the default partition layout. On my system /dev/sda1 was created solely for grub that is not normally mounted. To find it I did:
sudo fdisk /dev/sda
and within fdisk p to show the partitions. Next mounted that partition:
sudo mount /dev/sda1 /mnt
looked for the file with:
find /mnt -name grub.cfg
and finally updated the grub.cfg file with:
sudo grub2-mkconfig -o /mnt/EFI/fedora/grub.cfg
This process must be repeated every time the kernel is updated.
