The CEL usually has emissions issues for it to activate and, hence, the reason it can't test unless cleared properly.
My wife's Volvo just had a overdrive solenoid fault which shows on her computer overview, but doesn't show up as a CEL and I was still able to pass a smog test here in CA.

You do realize that once you pop a CEL, you have to go through a series of cycles before the system can be retested.

These all needs to happen for the PCM to determine the vehicle is ready for testing.

You can always ask the testing tech to verify whether it's test ready. If you don't ask them to check first and it fails, they won't let you know it's going to fail. They tell me it's against the "rules" to ask questions.
They can only answer requests.

Not usually, ALWAYS. By law the ONLY way the CEL can turn on is when a fault is detected in something that the EPA has dictated affects emissions. They have a list, and if one of those items has a fault the CEL comes on.
