Yes they can. In fact this could be important for LENR, should it be broad enough to include other boson quasiparticles, such as the magnon.
The definitions are similar: polaritons are quasiparticles resulting from strong coupling of electromagnetic waves with an electric or magnetic dipole-carrying excitation. The magnon could be imagined to be the subset of that - where the coupling is only magnetic. However, it may be only a partial subset with other features included. Polaritons describe the dispersion of light (photons) with an interacting phonon resonance; while the magnon would describe the dispersion of spin current with an interacting resonance. Using the same general terms, superconductivity where the Cooper pair is the boson, would describe the dispersion of charge within an interacting phonon resonance. (the last is my interpretation, which may not be correct). Thus we have a linking of three BEC phenomena which may happen either at room temperature or close- in the case of the RTSC.
