Unless I’m mistaken, this mostly depends on software/os you install.
A RPI with OpenWRT will be secured in exactly the same way as a router with OpenWRT and a laptop with OpenWRT. (At least I think so, I vaguely remember hearing about some Intel CPU vulnerabilities, but I don’t think there’s anything remote).
Power draw will be the main problem, along with more limited range because of the strength of the WiFi card.
