It is a little late but who knows if somebody comes across this in a google search or something, so;
No. It is not possible.
You need an optical encoder, hall sensor or other type of rotary encoder. See: [en.wikipedia.org] (or a linear but that would change the setup)
This limitation - Not being able to get a feedback of steps moved - is one of the biggest limitations to stepper motors in 3d printers because it is not possible to read-out missed steps and recover those.
