Can Google Re-Captcha 2 prevent CSRF attacks?

As the OWASP cheat sheet mentions, CAPTCHAs can be used as a way to defeat CSRF.

However, you've got me thinking. Maybe if an attacker combined a Clickjacking attack on the Google Recaptcha2 widget with a follow up from a CSRF attack on a page protected with Recaptcha2 for CSRF defense, then maybe this could work to the attacker's favour.

Update:

Having thought about this, the way that Recaptcha2 works is to return a value signed by a private key that can be checked server side. This requires the CAPTCHA displayed on the current form to be clicked, even if there's nothing to be solved. Therefore Recapcha2 should defend against CSRF. However, make sure that your hosting page has protection from Clickjacking too.
