Yes, neurologists can apply to the field, but they are at a huge disadvantage and face an uphill battle compared to radiology and neurosurgery applicants.
The best way in the future, to get into the field, IMO is neurosurgery > Radiology >> neurology.
When a patient comes in with a ruptured aneurysm with SAH, neurosurgeons will be consulted first. Also they can take care of complications and do IVDs and craniotomies (but if it comes to a craniotomy, chances are your patient isn't going to do well AT ALL). In the future they will be very well positioned in the field if it comes down to a turf war. For the time being, there are few radiologists and fewer neurosurgeons who are pursuing this field, there should be room for everyone for some time to come. As it is now most INR programs are run by neuroradiologists, or co administered by neuroradiologists and neurosurgeons. Rads and NSs will be favored over the neurology applicant.
Neurologists do not have the catheter skills or fluoroscopy skills and are at a huge disadvantage compared to other applicants. Radiologists should know the anatomy and fluoro as second nature. Neurosurgeons too have a knowledge of the anatomy and have rudimentary fluoro exposure from the spine work that they do.
True, neurologists they have the advantage in stroke care, but only a subset of INR patients are embolic stroke patients. Overall, neurosurgeons are well suited to take care of the sickest of the sick. My advice is that if you are serious about the field consider neurosurgery or radiology depending on what your interests are. Neurology is a distant third.
