Since Ubuntu uses grub, and if it works anything like Gentoo/Arch your kernel/bzImage should be located in your /boot folder.
simply do grub-mkconfig -o /boot/grub/grub.cfg, now if your distro hasn't made ganges than it's grub2-mkconfig but it's the same as before.
Than you can safely remove older kernels, also don't forget to do mkinitcpio -p linux otherwise you may have issues.
