These modern tires, not so much.
It wouldn't be a terrible idea to move it a bit every month or so. However, you're actually better off to NOT start the engine.
If you can ride it; ride it. That's great for it. But starting it and idling it, even for 15+ minutes, will not likely get the engine oil warm enough for long enough to boil off any moisture. And when the oil cools, it will eventually cool to a point that it produces condensation. That condensation is of course moisture, and it'll seep down into the oil.
Once or twice or even three times won't hurt anything. But some people have a habit of starting and idling their bikes in the winter for some reason, and will do it several times throughout the winter. Each time, while they are getting the oil up and circulating through the engine; they're also adding moisture into the oil every single time they do it. (When you ride it, it gets hot enough, and stays hot long enough, that that moisture all burns off).
I'm also not convinced getting the oil circulating is beneficial. The oil will run down leaving parts unprotected; but they're just as unprotected after 4 weeks as 3 months. Corrosion could be a concern; perhaps. But not likely an issue over a winter, or even storing for a year. Basically, if you start it every couple of weeks; you're increasing the number of times the engine is started with certain components unprotected. Instead of just firing it up in the spring and riding it, which means the engine only has to do that once.
So, if it makes you feel better; move it now and then. But don't start it except to ride it!
