It is possible to materialize a TARDIS inside the past version of that same TARDIS, but it requires overriding the Time-Track Crossing Protection Protocol circuit. If a TARDIS rematerializes inside of itself it creates a space loop, where the endo and exo-shell would joined. It should be noted that if the time setting is too high an Eigen Ram will occur.
If a Space Loop is successfully created, then the crew would be trapped within the TARDIS forever. The exo-shell is likely to undergo temporal drift, resulting in a distortion of the causality between the two interfaces. But it is possible to set up a controlled temporal explosion to escape.
