Yeah it is within that range but to keep the cars geometry the same you should fit the exact same offset wheels.
The offset is the distance in mm that the wheel face protrudes beyond the hub face and sets the centreline of force through the middle of the wheelbearing. Using too large an offset for instance increases understeer, eats wheelbearings and makes the tyres rub on the outer arch edges.
Too small an offset and the cornering gets too sharp and twitchy...not a wide range there tho admitedly
