It's also not the only cameo/gag video Capaldi featured in triplej's Hottest 100 Official Trailer (2015) in which he appears and goes into a Police Box.

I think it can be noted as part of the promo tour / Doctor Who live tour Capaldi cameoed in various videos, but it's not licensed or anything like that.
