Can you be addicted to procrastinating?

No: However, significant procrastination may be a sign of depression and/or adhd or other related psychiatric conditions.

Habits: Anything you do consistently can become a habit. So you can be procrastinating as a habit. I would not use the word addiction. I like this quote "“your beliefs become your thoughts, your thoughts become your words, your words become your actions, your actions become your habits, your habits become your values, your values become your destiny.” ― mahatma gandhi.
