In principle yes, it all depends on the way you look at it.
You can represent an right hand or left hand circularly polarized wave by a superposition of two orthogonal linear states with some phase shift.
Conversely you can represent a linear wave as a superposition of RHCP and LHCP states. It's simply a different orthogonal basis.
