I can think of a couple ways to do what you say:

- if there is a date/time command in GRUB, have the `grub.cfg` check the date 
and refuse to offer any booting options after that date (where I suppose the 
hardware-clock supplies that date)

- alternatively to "not booting", you could have it boot DBAN which will erase 
everything on all disks :-)

Or have a human manually boot the self-destruct option (which should require 
an administrator password probably)

(how do you expect to re-use these computers, if they have a nonfunctional 
boot-loader, by the way?)
