I signed up for Battlefield Labs as soon as the registrations opened, but I logged in with an email different from the one I have now on my account, which I changed due to concerns about the security of the old email. Will I still be able to play the open beta of Battlefield 6 even if the email I used to sign up for Battlefield Labs is different from my current account?
You should have used / created an EA Account to sign up for Labs, so as long as that is still the same for you, I do not see how changing your associated email address should change that.
Some players have discovered you can check your Early Access Beta status by requesting a download of your data in "Security and Privacy" within your EA Account Settings:

If you want to try that go for it, otherwise you could reach out to EA Help as well for assistance:
Hope that helps and see you on the Battlefield!
