Any x86_64 laptop known to support Linux should work.
Chromebooks are also suitable if they have been placed into developer mode and setup with Seabios so they can boot traditional linux distributions.
Be sure any Wifi/Bluetooth modules removed before the system is ever powered on for the first time. You may also want to consider sourcing the machine from a random retail store in order to avoid supply chain attacks.
