This has no effect with whether you can or not. All it means is that its MOST LIKELY not going to need as much cooling. but since it has 2 more cores, I would guess that the cooling required would be close to what the 8700k requires.
I would phrase that differently: a soldered core should mean it will be easier to keep cool because the heat is easier to transfer from the die to the cooler since solder is a better conductor than thermal paste/toothpaste.
However, it will still require as much cooling since those watts have to be removed. 100W is 100W either way, just like how a two GPU which consume, for example, 250W but where one exhausts at 60°C and one exhausts at 90°C will both require the same amount of cooling.
