Lenovo either seems to be an exception, or most of those whitelists include ath9k chipsets. See the reviews on this card, where none of them say “it didn’t work in my laptop”, but at least two say “it works better than the one it came with":
I looked specifically for ath9k, because those require explicit configuration by the driver (due to being softmacs). If there were any genuine concern about regulatory compliance associated with those whitelists, only hardmac chipsets would be allowed.
There are also motherboards with ath9k cards pre-fitted, still on sale in the US and Europe alike:
I found several models with AC support, but of course those use hardmac devices. Still, it is supplied in a mini-PCIe socket.
The cost of providing this seems to be so low that motherboard OEMs (who are normally notorious penny-pinchers) mostly don’t bother providing models *without* wifi support in the (extremely cramped) Mini-ITX form factor. Conversely, I can’t find any models *with* wifi included in the Micro-ATX form factor - though many do include an M.2 slot which could hold a miniPCIe card.
