I would say NO!   There is a possibility there is an input detector and will not allow it but why take a chance as it could also damage the PC. Get the correct adapter.  
I have a Dell Inspiron 5558.I bought adapter which has positive polarity..my original adapter has negative polarity. Now my question is should I use the positive polarity adapter on my laptop.
