Edit: although some people say the slide meant that the processor was coming for "devices like the SteamDeck", not literally the SteamDeck
"Some people" being Pierre-Loup Griffais, who works on the Steam Deck at Valve.

I doubt it, the Lenovo Steam-OS option is utilizing Ryzen R2 Go, which has the same RNDA architecture as Valve's handheld and pretty similar (though slightly better) specs.
There's newer architectures but they chose the same as OG Steam deck for... compatibility? Ease of OS support? Something else? I doubt Vavle would help Lenovo with support on a device they'd shortly eclipse with better specs.
Why wouldn’t they? It more or less locks the user into the Steam store where Valve gets a cut of every sale. That’s their primary income stream.
