Of course you can trash your hard disk if you boot prematurely,
but it has nothing to do with whether you do it by jumping
to FFFF:0000 or pressing Ctrl-Alt-Del or the Reset button.

(Sure some caches re-vector IRQ1 to capture C-A-D but that's
not the point. I can hardly think someone would write a batch
file or program that reboots without asking for a keypress
first, since any programmer should know background-write caches
exists, and as a matter of fact I don't think even straight DOS
will save modified files instantly.)
