In the thread @Sloop John B refers to, I pressed Phill Harris, but he wasn't in a position to confirm if Naim were supporting Roon Ready and Roon Core.
Putting aside operational and marketing reasons, you could make a good guess on whether or not Naim Uniti Core is capable of running Roon Core, by examining the Unit Core's specs.
Roon Core needs a reasonable amount of power so when they announced Roon Core on a NAS, it made the following reccomendation.
“Any NAS with a 64-bit Intel CPU is compatible, but to get the best experience, we strongly recommend a top-of-the-line (Core i3 or i5) NAS with expanded RAM (4GB or more).”
Mark Jenkins from Antipodes Audio indicated something similar when building their Roon Core product.
“I can tell you that the Roon guys look to us to write very efficient code, and that will help. But they do tend to assume a lot of processing resource is available and that Roon Server and Roon Ready will be on different devices. I suspect the good clean code plus RAAT is a lot of the reason for good sound.”
My best guess is that unless the Naim Uniti Core has a sufficiently powerful CPU and RAM it probably won't be able to run Roon Core anyway. Has anyone confirmed the kind of processor and RAM in the Uniti Core?
Assuming Naim's Uniti Core doesn't support Roon Core, you can still use a computer, NAS and soon a Linux based image with Roon Core which you can download directly from Roon, and install on a NUC for a dedicated turnkey Roon Core.
