Question Can Technics stereo systems mix and match ? (HD81, HD70 etc)

[Sling]

Can Technics stereo systems such as the SL-HD81 and the ST-HD70 mix and match? i.e. Can a CD player off one system be used to replace the CD player from the other ?

Technics manuals are usually available on the Panasonic web site.
