Such an update should pose no more of a problem than on an earlier computer or earlier updates (say, 11.04 to 11.10 on a BIOS-based computer). Of course, should doesn't always pan out in the real world.

In theory, you should (there's that word again) have been able to install Ubuntu 13.04 with Secure Boot enabled; since version 12.10 (including 12.04.2, but not 12.04), Ubuntu has supported Secure Boot. In practice, this doesn't always work, although I've not studied Ubuntu's Secure Boot problems in enough detail to know why. Certainly there's no need to enable Secure Boot for an update, though; there are plenty of EFI/UEFI systems that lack Secure Boot entirely, so it would be insane of the Ubuntu developers to require that Secure Boot be active in future updates. If you're booting with Secure Boot turned off, an update should still work with Secure Boot disabled.
