They can extend the length but you need to be careful and not exceed wattage per connector and cable.  Also the longer the connection the less watts its safe to send down a cable.  Wire size vs wattage is a hard science.  Pulling too much is a good way to damage cables, gear, or invite 🔥.    I would suggest short extension vs long … 4 inch (10 CM) extensions are available.  

But every connection is one more place prone to fail so fewer are better.
