Changing url of existing typeform

I'm using the free version of Typeform. I made a typeform and sent it out to people to fill in. And after that I changed the url of the form from the options available for free version. I know that the previous link will redirect the users to the new url, but,

My question is:

If somebody opened the typeform from their previous link on their browser and kept the tab open for several days, I now changed the form URL but they still have the old url tab open on their laptop. Will they be able to submit the form from the old url?
