Yes, the two concerns are having a cartridge installed which is CD-4 capable and low capacitance table wiring.
Since Dual sold the separate 1229Q table specifically for CD-4, it may be that the wiring capacitance in the regular 1229 may be undesireably high for successful CD-4 reproduction. However, it could also be that it is fine.
The only ways to find out is to either measure the capacitance with a suitable meter (look for 100pf or less) or just try it. If the carriers seem weak and the demodulator has trouble locking onto the carriers, it is an indication of high capacitance wiring before the demodulator. If you get good results, all is good.
