It most certainly could. Looking at the games you picked, there will surely be extra security measures. These measures could be anything really: only 1 ticket sold per person, no away team fans allowed, no online ticket sales, tickets only available to people who have a fan ID, ...
Usually (last season at least), the fan ID thing is not applicable to foreigners, meaning that you're still able to buy a ticket if you're not an Italian citizen.
There are exceptions to that rule however.
For example, if there's any sort of crowd trouble in the week(s) before those games, they'll probably be very strict and you'll end up being screwed.
Case in point: last season's Juve - Atalanta game. Regulations were as strict as they can be and there was no way of getting a ticket without the fan ID.
Problem is that you'll never know these things in due time. The Osservatorio usually only communicates the measures about a week before the game, 10 days at the very most.
I'd keep an eye on the clubs' websites to check for any press releases.
Also make sure to visit
http://www.osservatoriosport.interno.it/istituzione.html once in a while. They tend to give all the details, something which the clubs don't always do.
Shoot, if you have any other questions.
