I was looking for a winter romper bike, found a used one for sale that should make due

Here's the bike:

However, I don't like that drop stem for how I'm going to ride it.
It looks like a 1 inch stem.. so, I'm thinking I could simply swap it for a higher rise stem, something like this:

Question is: will that work? Simply swap out the stem or will I require other parts.
Assuming the handlebar radius matches (could get a new handlebar, if necessary, so this shouldn't be issue).
