I would probably do it. I gave three weeks notice one time and it was really a bit too much, but I'd felt that two weeks wouldn't be enough time. If you really can do it from home, this seems like a "best of both worlds" situation to me.

But if you are worried about "slippery slope" issues where it either becomes more involved than what they are saying, or they will try to convince you to do this for more than one week, then I might not do it.
