Sure. Run your table into the preamp that has the phono stage and then use either the preamp output or the tape output of that preamp to any line level input on the other preamp. If you use the preamp output, you can trim the levels with the voulme control. If you use the tape outputs, you will have a fixed output, but it will be a cleaner signal.
I have done this many times.
