There is a connection through the fact that they are both types of archetypal 'world pillar'. You might find researching Irminsul, Joachim and Boaz, mazzevot, and the Hebrew prohibition against erecting etz or Asherah by altars, interesting along with other world pillars. The medieval mind saw the Calvary Cross very much as a kind of tree, the Rood Tree (though Tree can also just mean 'timber'), see the Anglo-Saxon poem The Dream of the Rood. There is also the connection with Odin (he who hung on tree) and Christ through the manner of their apotheosis which also makes a connection between the Cross and the World Tree as the vehicle of that apotheosis.
In Qabalistic thought the Calvary Cross is seen as an axis of the universe and visualised as such in ritual, which again resonates symbolically with the idea of the World Pillar as Cosmic Axis.
