There are two problems with this:
1) The kernel will only boot if it's signed with a key in db, not a key
in MOK.
2) grub will read the kernel, but the kernel will have to read the
initramfs using EFI calls. That means your initramfs must be on a FAT
partition.
If you're happy with those limitations then just use the chainloader
command. If you're not, use the linuxefi command.
