Frames and wheels are just as strong
What you lose is the flotation of bigger tires.
Road Bike Party 2 - The Making Of Martyn Ashton's Colnago C59 Disc
On tires you lose the flotation and traction of a bigger tire. And a smaller tires is more susceptible to pinch flats. You have to be careful with a 25mm tire but as you can see in the video they push it pretty hard.
But for commute I would recommend a cyclocross and and put touring tires on it.
