Can dragons shapeshift or use glamour?

In theory, yes. In practice, unknown.

Magic in the XIV universe is basically all powerful. In theory you can do anything if you have enough skill and aether. Dragons, especially the older ones, presumably have both of those things in abundance, but we don't know how much skill and aether a transformation like that would take.
