Totally. Usually all weights have the equivalent nodes and curves in their bezier paths, so that intermediate weights can be interpolated between masters. The only delta in size you would get is if the joining/flattening of these paths resulted in different nodes in the exported fonts. As different weights typically include the same open type feature code and glyph set, I’m not sure anything else would cause much variation in size.
