Highly doubtful - the same switches were used for fog lights in the 2012 and swapping the switches DID NOT enable the fog lights, even though the wiring out of the BCM was there.
I suspect at MINIMUM you would have to swap the switch and have the dealer flash the appropriate section of the as-built codes from a 2013 similar car.
More likely the BCM's are probably different and you'd have to swap in a 2013 BCM - and I'm not sure that would even work.
Sorry for the bad news.
Other possibility would be the BCM always had wiring for the switch and circuitry for it and you just have to install the switch to get it to work like you said.
(Ford does some odd things sometimes - you have to re-wire the entire car to add factory fog lights (and then you still can't use the factory switches), but installing cruise control is just a matter of swapping the steering wheels so you have the correct activation switches - go figure!!!)
Good news is there likely isn't any additional wiring to run - if it does work.[popcorn]
