In Portugal, there's a clear distinction between village and hamlet. The wiki you mention has a text regarding Brazil and another one regarding Portugal (both in Portuguese).
In Portugal, a village must be admin_centre of "freguesia" (the smallest admin division) or an historic admin_centre. Capelas isn't neither, so it should remain as hamlet.
For more information, you can check the official wiki of the Portuguese standardization:

Any doubt, don't hesitate to answer here or contact me.
