Can domain administrator access local administrator data?

If a PC is added to Active Directory, but I log in as local admin LA. Would any Domain Administrator be able to access any local admin LA data? (such as user folder or revealing Chrome Stored Passwords)?

I tried revealing a chrome password using the domain user DU (That has admin rights on the PC) but Windows refused it.

Solution 1:

By default, the "Domain Administrators" group is added to the local "Administrators" group of a computer, when you join it to the domain. Unless it was removed or changed, the domain admin can access anything on the local computer.

Chrome encrypts stored passwords, and probably with a key derived from the user account it was stored with. That would explain why you can't access the passwords.
