Working with Trados 2017 and Trados 2019 on 2 different computers

Hello,
I have a question about the installation of Trados on a new Computer. Actually I'm working with Trados 2017 on a laptop. Few months ago I have bought a desktop and I would like to install Trados 2019 for which I already purchased the licence some months ago on this new one. Once I have installed and activated my new Trados 2019 licence, can I still work on Trados 2017 on my laptop?
