I don't think it was a lie, per se. In practice, the Dunlendings did feel aggrieved by an age-old land squabble (and we certainly can put that sort of disagreement in a real and very modern historic sense). I think it was exactly what they wanted to hear, given impetus and gravity by Saruman's gift of gab.
