Yes. With everything in place, just not powered, of course.
Another interesting feature is that it is also possible to tune the 
system to the other resonances of the secondary coil. Just tune the 
primary coil to them (use a variable capacitor, or associate several 
common capacitors, since the measurement is at low voltage), and the 
beating waveform appears, at higher frequency. A simple way to see where 
the other resonances are without need of loading the secondary coil with 
probes.
