Is there a nomenclature for linear alkanes with n carbons? Is there a common nomenclature (not necessarily IUPAC) for naming linear alkanes with $n$ carbons without resorting to Greek/Latin numerical prefixes (hex-, hept-, etc.)? 

For instance, is there a name for the higher linear alkane of $\mathrm{50}$ carbon atoms other than n-pentacontane? ("Not necessarily IUPAC" is meant in the same sense that $\alpha$, $\beta$, and $\gamma$ nomenclature  don't follow IUPAC rules but are nevertheless often used to designate relative positions of carbon atoms)
This does not answer you question, just mentions an alternative name that does have that count arabic numeral in the name, but is not eliminating the greek/latin prefixes. One could use IR-7.4 INORGANIC CHAINS AND RINGS nomenclature that would be impractical, e.g. the mentioned n-pentacontane would become dohectahydridopentacontacarby[50]catena or maybe even 1,1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,9,9,10,10,11,11,12,12,13,13,14,14,15,15,16,16,17,17,18,18,19,19,20,20,21,21,22,22,23,23,24,24,25,25,26,26,27,27,28,28,29,29,30,30,31,31,32,32,33,33,34,34,35,35,36,36,37,37,38,38,39,39,40,40,41,41,42,42,43,43,44,44,45,45,46,46,47,47,48,48,49,49,50,50,50-dohectahydridopentacontacarby[50]catena (not to confuse with catenanes).
