Popping a pimple on your nose is not recommended as it can spread bacteria which can cause more pimples to break out on your nose.
However it's okay to pop a pimple as it will not harm you to pop the pimple on your nose.
So if you want to pop the pimple on your nose then you can do so.
However if you do pop the pimple on your nose make sure to wash the area where you popped the pimple and also apply some hydrogen peroxide to kill any bacteria that could be on your nose from the popped pimple.
I have popped pimples on my nose before and as long as I use some hydrogen peroxide on the popped pimple and make sure to wash the nose after popping the pimple it has never been a problem.
