Nah, I don't think so.
They'd be entering R&D around now and by the time it'd come out they'd be releasing the PS5 real soon, wich sort of defeats the purpose. The tech is also not nearly close enough to make a fully fledged PS4 portable, they'd have to go with a mobile chipset, wich again defeats the purpose.
Also Nintendo probably has some sort of exclusivity deal on the Tegra line with NVDIA, wich means Sony would not have access to the most powerful mobile chipline going forward either.
Unless they straight up go the Nintendo route and make their next console a hybrid, wich will probably sit inbetween the PS4 and the PS4 pro powerwise this just isn't technically feasable. And even then it's probably not a smart move.
