People use the word tunnel (or their equivalent word) in different countries in various contexts; many times these do include all or most passages through anything, when they are narrow relative to the length. It's then only natural that they use tunnel=building_passage or even tunnel=yes when they map these, totally without any regard to whether some engineers or geologists or encyclopedia editors have restricted the use of the word in their field in English to only under ground level tunnels.
