In the exact same sense that potatoes and carrots are tubers, and yet are also vegetables. That they belong to a refined sub-class doesn't deny them entry into the enclosing class.
U. S. Supreme Court, Nix v. Hedden in 1893 challenged the Tariff Act of 1883. The tariff levied a tax on imported vegetables but not on fruit. The Nix family tomato vendors were suing to recover back duties paid under protest. The court decision declared tomatoes to be a vegetable (in common speech) for tax purposes.
