Sure, but I'd argue that's because the key signature is wrong. The correct way to notate that is with either a modal key signature a la Bartok or notate it as D with a constant natural on the C, showing that the tonal center is D while clearly notating the departure from the traditional major scale.
By this standard probably something like 30% of the music ever written has the wrong key signature -- and I've never seen a piece of non-major music with a correctly notated key signature!
