it could yes. Is it likely from doing a couple of pulls with the dizzy advanced?....not really.
Make sure you know how to detect detonation before messing with the dizzy, b/c if you advance it too far the engine will detonate and you take the chance of ruining your engine. Too far advanced will also cause the EGTs to go up beyond safe limits (which can also cause damage).
I wouldn't just turn the dizzy randomly without the use of a timing light, with a timing light you will at least know how far you advanced/retarded the timing. Oh and make sure you jump the service connector by the ecu (2 pin plug) otherwise as you turn the dizzy nothing will happen b/c the ecu will be automatically correcting the timing back to 16 degrees BTDC.
Turning the dizzy towards the firewall is advancing, turning it towards the radiator is retarding it.

use a timing light and stay within a couple of degrees...

problem with this method instead of tuning with crome for example, is when weather changes, air density, altitude... you may be too far out of range for the ECU to correct... as I'm sure there is some kinda limit in terms of what the ECU can do and what is controlled by the physical position of the distributor body vs. camshaft position.
