Yes it's possible with enough links, quality and quantity.
I beat the wikipage for my main keyword, the monthly exact searches is 12k as well.
My site is PR2 and 3+ years old (bought old domain)
I use various linkings from linkwheel, my own profile links scheme, article directories, blog posts, manual comments, and xrumer profiles.
Not all links point to my main site, some to the web 2.0, some to inner pages, articles, blog posts....
Currently I have around 1.5K links (LD) and 1.2K (LP), around 25% of them are sidewide.
In content contextual link is important.
I know some 'experts' say 'anchored link' is the most important thing, but anchored contextual link will give more power.
As well as giving more power to your direct links by giving them links.
