Not necessarily. The move to more megapixels (eg 36MP) heightens the risk of blur, even in FF.
Nikon made a big deal of the whole issue when the D800 was released, and even felt the need to release a 'technical guide' document for the D800/E to steer people (particularly 12MP D700 upgraders) around the hazards of shooting at such high MP:
'At the high resolutions offered by the D800/D800E, even the slightest camera motion can result in blur...', with all sorts of [sometimes rather obvious] tips about minimising blur.
