No, Roya is not a Wiccan name. Wicca is a religion, and not a culture. Names come from cultures, not religions.
However, if your question is asking whether or not the name Roya is an acceptable magical name to use in Wicca, I have no idea. Hopefully a Wiccan will come along and answer this second part of the answer.
[edit from a Wiccan] As far as being acceptable as a magickal name, if the name Roya calls to you then by all means use it! Pretty much anything is acceptable as long as it has personal meaning and isn't the name of a deity. (that would be disrespectful)
