They could easily give away the PS4 version of the game for free as long as you provide a proof of purchase for the PS3 version. You could just enter the barcode, receipt transaction number, or the product number on the disk in the promo code, or some other interface they provide, so they could verify it. And after it has been entered once, they can easily keep track of it and prevent people from entering it twice, like when you register a software product license.

Bandwidth costs money and Microsoft/Sony wouldn't allow to do this for free. Gamers have shown they're willing to pay full price for HD rereleases, so it would be foolish for Microsoft and Sony to pay for bandwith when instead they could also ask for $70.
