Does a centre-loaded HF antenna need radials? If I put a loading coil 1,5-2m (5-6,5 feet) high, do I need to put radials out on the ground? Feed point would still be near the ground.

In short, yes, if it is a current-fed antenna, i.e. a quarter wave, or odd multiple thereof (3/4,5/4, etc.); if it is a λ/2 antenna, or even multiple thereof, then no, it does not need radials.
Whether or not your λ/4 HF vertical antenna uses a loading coil, it will benefit from radials, but at a minimum, must have a counterpoise.
