Hi
yes it can it is twisted pair less cross talk
Typically cross talk isn't a problem in the home because the line usually isn't running along side any others to cross with.
The only thing twisted pair 'patch cable' will help with is if the line in the home from the socket to the modem is picking up interference locally, again often not the case over such a short run. Twisted pairs don't stop interference, the twists are there to ensure each wire picks up the same amount of interference. Provided the interference is the same in both wires, it gets cancelled out. So just a flat cable might twist and turn enough to do the same thing. Interesting article here
https://en.wikipedia.org/wiki/Twisted_pair, twisting cable essentially started back in the 1880s on telegraph poles.
Other things that may make more of a difference is conductor size and quality of the connections, but only if the previous cable was particular poor.
Also just the fact the cable is a different length, i.e shorter OR longer even can improve or degrade the connection slightly, this is all to do with reflections of the signal and if it is in phase or out of phase etc and impedance changes. Very much a black art and no one size fits all.
