Actually LG made the Nexus 5, Moto did the Nexus 6, developed while Google owned Motorola and released a few weeks after Lenovo bought them.

Depending on your definition of 'small', your only hope might be if they did Razr and you used it folded up. That's credibly small, though I don't know if Graphene would be game for bothering to do that sort of multiple display work.
