It is not, it is the only relevant part here.

You should expect compatibility issues with every major/minor PHP upgrade/downgrade.
We cannot fully answer that questions because it completely depends on the code the specific webapplication is using. So you should better ask if your specific wordpress version is completely compatible with PHP 5.6 and PHP 7.0
PHP releases Migration Guides for every bigger Version, so maybe this should be the first ressource to get a feeling for compatibility issues
