Yes. You can use Pasco carts on Vernier tracks and vice versa.
The only limitation is that the Vernier Encoder Cart requires the addition of the Motion Encoder Long Track Strip (METS-LONG), to the Pasco track for operation of the encoder. See Will the Motion Encoder Cart and Receiver work with a Pasco track?.
The simple Vernier dynamics carts and the Vernier Sensor Carts work on Pasco tracks directly; Pasco carts work on Vernier tracks directly.
