Oh no. On the contrary, that is challenging the equivalence principle. Since it is stated that there is no way to tell the difference.
I don’t view it that way. I read Einstein’s model of the equivalence principle to be based on a uniform gravitational field, the grav field of a planet is not uniform so you can tell the difference.
Instead of the iron bar idea think about dropping a handful of marbles high above a planet’s surface they would slowly spread out in the direction of the planet (radially) but draw slightly together tangentially as they fall.
