Android permissions and linux permissions

Are the rights to android (the ones you request in the manifest and represent during installation) the same with the linux permissions that the root user gets on the root phone?

More precisely: if I have root on my phone and I have an application that wants to make a call but has not requested permission for this in the manifest, will the call succeed or the application crashes?

Thank.

Some Android permissions are implemented as Linux permissions (for example, External Storage or Network, each membership in a Unix group that is allowed to perform these operations), while others are fully implemented in Android layers.

In fairness, it is worth saying that all these mechanisms work together to enhance the security of Android as a whole.
