Yes, but the Episcopal person will probably not be able to have a funeral in a Catholic church. The spouse of a Catholic who is not a Catholic can be buried from the Catholic Church if that person has lived a good and Christian life. It happens quite frequently.

Roman Catholic AnswerChristians
Provided the dying person is of the Catholic faith, absolution is a blessing given by a Roman Catholic Priest, forgiving any sins the dying person may have committed in life and for which the dying person repents.
The question, as asked, makes no sense. The Pope is the Vicar of Christ and universal bishop of the Catholic Church. In a certain sense he is the Catholic Church as he, in his person, represents Our Blessed Lord, Jesus Christ, Whose Mystical Body IS the Catholic Church.
ExcommunicationRoman Catholic AnswerI could be wrong, but I don't know of anyway to remove a person from the Catholic Church. If a person is a Catholic, then they remain a Catholic, subject to all the laws of the Church until they die. An excommunicated person is under a specific penalty in which they can not receive the Sacraments or be given a Christian burial, but they are still required to attend Mass, and abide by all the other regulations. A person may remove themselves from the Church's jurisdiction, but they are the only ones who may do that - the Church cannot.
