Yes.
I'd go as far as saying Cheshire for positioning the secondary, then star test for titling the primary

But a well-collimated laser is very convenient.
The Barlowed lasers don't just remove errors due to off-centre holding of the laser but also due to crooked focusers, drooping draw tubes etc. But if you're sure your focuser is square any accurate laser will do.
