If you follow the link to the model in their page, it selects the default version with Windows 11 PRO. You can explicitly choose Ubuntu, but it‘s not the default. My point here is „acquiring the license for a windows based laptop is a non-issue if you‘re willing to spend the 70USD it costs.“.
The problem is generally less the individual pro license and the associated enterprise licensing costs that come with managing said device in Azure AD/InTune.
