If the COF of the wheels is too low, then you'll be able to push them regardless. If you're running blue nitrile and they're using (insert something with a COF of 1.0 or lower here) and they weigh the same as you, then of course they will move around. There's no magic in an x-formation.
However, there is no way to avoid overcoming the friction of the wheels if the swerve is locked in such a formation. Unless you push with enough force to rotate the modules out of the formation (extremely unlikely), you are basically dealing with the whole weight of the robot times COF. If you can overcome that, then bully for you.
If you push only the corner of the swerve, then it might be easier to push versus a head-on assault.
As an aside, putting the wheels in such a formation makes it very quick to rotate the modules into their next position, making it an ideal rest position as well.
