Cause I'm a renegade! Never been afraid to talk
About anything, anything, anything, anything, renegade

from Jay Z (Ft. Eminem) – Renegade Lyrics on Rap Genius

Meaning

He has no qualms rapping about anything, no matter how offensive society considers it.

Both Jay-Z and Eminem have made many songs that either challenged social order or drew criticism for being downright offensive.

Examples include:
99 Problems
Mosh
3 a.m.
Hard Knock Life (Ghetto Anthem)
Kill You

The way Jay-Z questions “anything?” after Em says “anything”, is a reference to Jay’s song Anything. The chorus sampled in Jay’s song sounds just like Em in Renegade.
