many people advise to not remove the previous kernel in case of issues with the last kernel.

I have never had to go back to previous versions, but yes, it's possible.

If someone doesn't want to actually remove the kernel, but rather just it's listing in the grub menu, you can delete the kernel's entry at the bottom of the menu.lst file. To open the file type the following:

sudo /boot/grub/menu.lst

Just make sure to double-check that you're deleting the right one!

Problem with this approach is that this file will be overwritten every time a new kernel is installed. So it's only a temporary solution... You can do it though.
