I think KFC invented/patented the combi-oven, they could be referring to that. (A humidity/temperature controlled oven that can be used like sous-vide.)

Practically I kinda doubt you'd want frying temperature anywhere near a computer, but you should be able to get warm enough to safely hold already cooked chicken.

Edit: I think this is the KFC patent for the combi-oven: https://patents.google.com/patent/US5077065A/en
