The location of the electron is part of the description of a quantum state, so if two electrons do not have the same location they are not in the same quantum state. Whatsoever, they can of course be in the same quantum state with respect to the other quantum properties (energy, momentum, angular momentum and spin), but their complete wavefunction won't be the same.
