Probably not, because lots of the tiles would need to be rendered
especially for you.  tiles.openstreetmap.org basically only renders
tiles that are "looked at" at all, so bulk-requesting areas will force
large areas to render to the highest detail.
So either you put up a tileCache, or, better yet, render tiles yourself.
It's not *that* hard to set up if you have your own server.

This is not official word on this, the admins (like TomH) get the last
say on this.
