I don't think so, it's a one time event unless your server owner spawns another one in manually. In Tekkit Classic some weird bug allowed multiple enderdragons to spawn in the end, I saw up to 20 at once, I don't know which mod caused the conflict though and I haven't been to the end in Tekkit Lite so presumably they fixed that one...
