Is it appropriate for boys to wear shawls?

Yes, as long as it is properly matched, no problem. If it's a plaid shawl, I suggest you use a black and white plaid with a short black trench coat in Korean double-breasted style. Pants are recommended to be jeans or thin pants that can reflect the leg lines. You can try to match it. Here are some pictures for your reference.
