Include tagging when exporting PDF from InDesign will make it more likely. For example, if you choose High Quality Print or Press Quality PDF presets, Create Tagged PDF should be checked on the General panel.
I can't guarantee that Acrobat will read that as a list, but it makes it more likely. The latest version of Acrobat Pro DC includes the feature of creating a list if one doesn't appear in the PDF file using the Edit PDF tool. (You need to apply the update released in October 2015.)
