No, a tomato and potato cannot be crossed, at least for now. However, genetic engineering may some day make it possible to combine potato and tomato genes. It is possible however, to graft a tomato shoot on a potato rootstock to form a single plant. That is done sometimes as a novelty or for research purposes. A grafted tomato-potato could produce both tomato fruits and potato tubers on one plant. Reference Garner, R.J. 1988. The Grafting Handbook. London: Cassell.
