A tunnel would be different from subsurface mineral rights. Landowners retain rights below their land. https://en.m.wikipedia.org/wiki/Cuius_est_solum,_eius_est_usque_ad_coelum_et_ad_inferos https://en.m.wikipedia.org/wiki/Cuius_est_solum,_eius_est_us... I'm also interested to know if this is in a right-of-way or Musk is buying rights from individual landowners. My guess is right of way.
