Yes, you can unlock the 10 lapper. However, be prepared to have to upgrade your R18 in order to be able to win enough races to unlock it. The PR requirement for the 10 lap events is 86.0 (well below even the base PR for the R18, 919, and TS040), but the races that lead up to it require higher PR levels.

Unfortunately, the R18 isn't the cheapest way to get there, but since it's what you have, it's likely cheaper to stick with that than to buy the 919 (the cheapest option upgrade-wise) and then have to upgrade it as well.

See this link for more info on the most cost-effective way to get to 100% in every series:
