Yes, you can. The dealer will process the necessary paperwork to pay off your vehicle and any related fees.
No. It's owned by Honda still until you execute your option to buy. You can sell your option to buy though. Which gives someone else the equity you have gained with lease payments. But you would need to purchase and hold the title to the car to sell it. I would talk to the dealership, they are providing good deals to get leased cars back to sell.
