If you want to try it, sure. But when you pry up flooring, what usually happens is the tongue splits where the nails go through it. If it doesn't great. But what usually happens is the nails stay in the underlayment and the tongue splits. So, if you want to re-use the flooring as flooring, you almost have to take a recip saw along the underside of the pine flooring and cut the nails. Of, if you really don't care to reuse the flooring as flooring, and just want it for woodshop projects, then don't worry about the tongue splitting. Let her split. You'll rip the tongue off on a table saw anyway.
