CluckingBell Speaking as a former teen, absolutely. "Adult" is just a marketing label, not a restriction. There really aren't many books marketed to adults that could be deemed unsuitable for a teen, except as reading interests vary from person to person. Some people may never enjoy literary fiction, others horror, but often our reactions change as we age, and we get different things out of each book at different times in our lives. If a teen has an interest in a book now, they should read it now. If you are the teen in question and have specific concerns about content or subject matter, you can always explain what those are so they can be addressed by someone who has read the book.
