Yes, you can attend a nondenominational church irrespective of the denomination of Christianity. A non-denominational church allows people from every denomination to come and worship in their ways and methods, giving them the freedom of worship. It is believed by the members of a non-denominational church that every Christian has a firm belief in God and Jesus Christ that makes them United and the same in every aspect. Hence they worship and believe that the church is based on the teachings of the Bible only. Every Christian has the right to attend and worship at a nondenominational church without anyone pointing out their ways and methods of worship. Each church member has the right to worship and offer prayers at a nondenominational church.
