Linear acceleration caused by a force applied outside the center of mass

I´m trying to figure out, how does Newton's first law work when the force is applied outside the center of mass. Does it have any effect on the object's linear acceleration (not rotational)? If it does, how do I calculate it?

Imagine that a force $$\vec F$$ is applied to a body.
The line of action of this force does not pass through the centre of mass $$C$$ of the body.
Apply two forces $$\vec F_1$$ and $$\vec F_2$$ at the centre of mass of the body such that $$\vec F = \vec F_2$$ and $$\vec F_1 + \vec F_2 =0$$ as shown in the diagram below.
You now have a force $$\vec F_2 (= \vec F)$$ acting along a line through the centre of mass of the body which will only produce a translational acceleration of the body and a couple consisting of the two forces $$\vec F$$ and $$\vec F_1$$ of magnitude $$Fd$$ which will only produce a rotational acceleration of the body.
