Although you can update a kernel, it's usually a bad idea.

generally, you should install new kernel, reboot, if no problems with a day remove old kernel
I would keep them longer than that. You might not thoroughly test a kernel within just a day or so. And an update to something else, afterwards, might present a problem between it and the new kernel. I think it's always best to keep at least one or two prior kernels.
I guess running NOC's for years has taught me that you have backups for more than one reason. Typically each machine has a kernel source kernel install, the .config is copied into new ksource and re-made, not much can go wrong.
I stopped using RH supplied kernels at around RH4, when a RH update of the kernel _did_ in fact break things... Since then I've rolled my own, and never had a single glitch, and I apply that rule not only to the fedora desktops, but also to every server I manage (none of which run fedora/rh).
