Major French computer store LDLC (and its subsidiary materiel.net) sells modern laptops with FreeDOS preinstalled (so you don't have to buy Windows). I wonder if that's something others do as well.
Though with a quick glance at current local computer retailer catalogs I found only HP 290 G3, which is not a laptop (https://www8.hp.com/h20195/v2/GetPDF.aspx/c06636833.pdf). Found plenty of discontinued laptops (e.g. HP ProBook 430 G6: https://support.hp.com/lv-en/document/c06179691), though, so maybe it is just not as common anymore. I vaguely remember seeing FreeDOS laptops much more often 5-10 years ago.
