According to this from here you can use it.https://support.google.com/work/mail.../6233342?hl=en

After you create your business email address
You continue to sign in to Gmail with the same username and password
All of your existing emails and contacts stay intact
You continue to send and receive email from the email address you prefer, whether it’s your business email or your original Gmail address.

And it says this here:https://support.google.com/work/mail..._topic=6296469

To start using your new business email, just sign in with your existing Gmail address and password, or your new business email and existing Gmail password. When you compose emails, you can choose to send from whichever email address you prefer—your new business address or your original Gmail address.

Also, I figured out that me having family sharing set up on my personal email account was blocking me from signing up for "Business email powered by G Suite." When I turned off family sharing I was able to clear the initial hurdles at this link, though I did not fully sign up. https://www.google.com/apps/signup/u/0/gmail/country
