Can I use this adapter with my MacBook Pro while docked in a vertical stand? Or does the laptop display have to be open?

Yes, you can use a MacBook Pro while it is closed. Read about it in Apple support document HT201834 "Use your Mac notebook computer in closed-display mode with an external display".
