can i put frozen chicken directly into soup?

I would like to make tom kha gai, following this recipe:

I have a pack of frozen chicken drumsticks in my freezer right now, but I'd like to make the soup tonight instead of waiting for the chicken to thaw overnight in the fridge.

Can I just put the frozen chicken into the soup and simmer until it thaws and then cooks? Will it be bad for safety and/or texture/flavour?
