setishock on "Footer text"

I'm using a theme that has been marked with a blue ?. The text below the description says the theme has been abandoned.

My question is this:
If the theme has been abandoned and is 6 years old, can I remove the reference to the coder and just leave the link to zenphoto? I am altering the theme to black and the footer text just looks tacky.
