Distortion in the resonance region between fb and fh would be less, because cone movement is reduced in this region. That will help between 50Hz and 100Hz. If desired, one can further reduce distortion by removing any chance of delivering information below the system resonant frequency. Since the speaker system unloads below fl, there is no output generated and so there's really no point sending it any input. So a high pass filter can be employed set to fl to further reduce distortion. But the direct answer to your question is that - Yes - a bass reflex speaker generates less distortion than a comparible sealed box because excursion is lower.
