Yes, different cameras and different films have different levels of dynamic range - but HDR is a post-processing technique, independent of camera. If you're talking about the "HDR look", as most people are when asking specifically about it, that is a look is not like any unprocessed photo from any camera, no matter the range... the "tone mapping" is the big difference. Even in HDRs made to look realistic, IMHO they still tend to show effects like distractingly bright shadow areas and so often the dreaded halos that wouldn't be there in a camera with high dynamic range.Dynamic range is not quite as simple as it seems and "HDR or not HDR" is not clear cut. Of some currently available dSLRs dynamic range can be from 13.7 stops down to 10 stops, in other words a single exposure from the first camera would cover about the same range as the second camera would if set up for HDR with +/- 2 stops!
Further, the maximum dynamic range is only at the lowest ISO and gets progressively smaller as ISO goes up, dropping to about 9 stops at 1600 ISO. Because of this it is not feasible to look at an image and clearly say "HDR" or "not HDR" since the same scene can be rendered very differently by different cameras or even by the same camera at different settings.
For example, look at samples from the Fuji S5 Pro, which has almost 12 stops of DR (even in jpg!), versus the usual 8-9 of most DSLRs (without tweaking in raw.) They have a ton of DR but look nothing like your typical HDR photo. IMHO the big difference is way the highlights and shadows "roll off" - smoother than on most DSLRs.
Dodging and burning is fine but you can do that in post-processing easily especially with Lightroom 2... without producing the "look".
