If either of them had said 201 years then no, as this is a very specific number. But they didn't.
Look at the timeframe mentioned in http://www.newscientist.com/article/dn26041-proof-confirmed-of-400yearold-fruitstacking-problem.html#.VZOL-vlQ3oC article. Notice that the article specifically mentions a 400-year-old problem, whereas the actual dates are 403 years apart. This would still have been a valid representation if the difference had been, for example, 408 years, or even 417 years. Also note that this has been posted on a scientific website, implying a greater level of accuracy and verification than most sites. Interestingly, the article later mentions a '300 page document' that took 12 researchers 4 years to verify. Again, do you really think that this would have been exactly 300 pages long? And that the researchers spent 4 years to the day checking it? Of course not. And so it stands to reason that Todd/Pete could also be 'rounding up' or 'rounding down' the exact time since the great war.
A very interesting point. Note that you rounded the actual difference of 36 years and 23 days between start dates, as verified by the http://fallout.wikia.com/wiki/Timeline#2241, to 'around 30 years'. Now, if this had in fact been slightly less, say 32 years, then you could just as easily have said '30 years' for your statement to be correct. But you used the word 'around', meaning 'approximately', due to the actual timeframe being midway between 30 and 40 years. Based on this, I am fairly confident that my suggested timeframe of 208 years still stands.
The release date for Skyrim was 11.11.11, which if we 'condense down' can easily be made to read "1.1.1". Also, the actual release date of Fallout 4 is (in US notation) 11.10.15, which again, if we take the first digits only, gives us "1.1.1". This second example may possibly even be seen at the end of whatever new trailer we are shown closer to release, most likely morphing the number 111 into the release date itself. Finally, the use of "111" as the number of the vault in Fallout 4 could be a reference to the 3 main protagonists in Bethesda's 3 Fallout titles, namely the Lone Wanderer, the Courier, and the Sole Survivor. As in 1+1+1 = 3.
