No. He has the authority but it is not yet his time to rule.
1:6 When they therefore were come together, they asked of him, saying, Lord, wilt thou at this time restore again the kingdom to Israel?
The apostles understood that Christ was going to establish a physical, earthly government. They asked him point blank, after his resurrection, if now was the time.
Acts 1:7 And he said unto them, It is not for you to know the times or the seasons, which the Father hath put in his own power.
He says in effect "No, it's not for you to know when."
Daniels vision in Daniel chapter 7 also affirms the establishment of this earthly kingdom. He has a vision of 4 earthly kingoms, once occurring after another. In the end another ruling power replaces them. The chapter is too long to cite here, but read it. It in no way indicates a vague, spiritual rule, but instead an earthly kingdom.
Also:
Mat 4:8 Again, the devil taketh him up into an exceeding high mountain, and sheweth him all the kingdoms of the world, and the glory of them;
Mat 4:9 And saith unto him, All these things will I give thee, if thou wilt fall down and worship me.
Here Satan offers kingdoms to Christ. Christ doesn't say "they aren't yours to give liar." They are Satans kingdoms by the assent of God not the power of Satan. All power is given unto me in heaven and in earth.
Having all power and exercising that power are not the same thing. God has not exercised his authority. The United States has the power to expunge Sadaam and rule Iraq. It has not exercised that power yet. In the same way Christ has all power and authority but has not exercised it yet. He will though.
