My answer would be, that depends.
If it's something that can be grumpy to start, runs a bit rich, and is likely an expensive engine, then yes, I would. But there's a few reasons why.
Sumps aren't really sealed, there is airways to them, so it is technically open to moisture. Secondly, if as mentioned it has been started, and it's a fuelled up, I'd dump it, as chances are, fuel is in the oil.
Next to that comes, how much use had said oil seen before it was parked up. IE, how much carbon, and potentially fuel/water did get in there while it was being used, and has now been allowed to sit, and slowly come together?
For the most part, if it's just been something like a road car, stock engine, nothing wild, f**king send it if it's not near oil change spec.
