To date there is no clear requirement for Oculus Link on laptops.
The simple "need a USB 3.0 port" seems to not be enough to get Link working on a number of laptops, despite many fixes, adapters and so forth.
I understand that laptops are a pain when it comes to which graphics card is used, however the official Link cable ends up being an expensive skipping rope. This depsite many laptops being able to run PCVR games without breaking a sweat. Fix your software, please.
