One that came with the receiver is too short, can I use a stereo extension cable?

10' isn't bad. It's the long runs of cable that will allow self inductance and shunt capacitance to grow to a harmful amount for low level signals. A mic cable will be pretty sensitive to this, since that's a tiny signal in the mV range. Also goes with the quality of cable, the better the cable the longer you can run it without degradation.

Onkyo was completely worthless, customer support stated they have no info and cannot recommend any solution to extending the mic cable. So, can someone point me to a recommended cable? A 10' should be fine.

I found this one, seems pricey for a 6' extension but then I need a good cable too...

lol, $10 is cheap. I think you should just get a cable and try it. It probably won't add much more error to the system than what's already there.

If it makes you feel any better I use a cheap 20' car audio RCA on my SPL meter when I take REW sweeps. Not as big of a deal for that, since sub measurements are LF. Using the long cable for higher frequencies is more likely to encounter problems, but I doubt it'd be a big deal even for your purposes.

I remember in a training that the trainer had a 50' cable that he made himself and said it was ok as long as it was of decent quality.

Page 98 of the manual for your Onkyo TX-NR3007 AVR indicates you can see and adjust the equalizer manually, after you go through the automatic setup on page 61. You would only have to tweak the 16000 Hz band, if you have to do anything. When you are doing the Audyssey setup, for the purpose of this test, be sure you never move the microphone, because you won't be able to repeat the placements accurately.

After you have tested the extension cable you should re-do the Auydessy setup using the 8 positions corresponding to your seating. You will get a different result, but the correction you need, if any, will be the same number as before.

If you have questions about the Auydessy DSP in your AVR, you may want to direct it to the Auydessy thread.
