The way it's being asked here, then I would say "not really". But there are some interesting examples along the outer edges of the argument that can be delved into:
1. SENIORS: when we view senior citizens in their 80s and 90s in senior living centers, we see men and women engaging in traditional friendships much more freely. Is this because at at that age, the pressure to pair bond and mate has been reduced?
2. WORKING ENVIRONMENT: when we add the overarching pressures and mores of the corporate world, it's more common for men and women to engage in typical "friendships" than when we remove that artifice. The gain (financial, power, status) to men and women engaging in inter-sex friendships (without intercourse) far outweigh, in some cases, the gain that comes with pair bonding and intercourse. So, men and women able to repress standard physical urges seek friendships to create situations of mutual benefit that create financial and status gains in the workplace. For example, Jim doesn't know as much about cash flow analysis as he rightfully should, but needs to get better at it if he's to be promoted to senior accountant. Jane does present-value-of-future-cash-flows in her sleep, but lacks some of the coding wizardry in python that has allowed Jim to climb the ranks quickly. Both have something to gain by be-friending each other and sharing; both have decided it's best to be friends to win the war in corporate and learn that each of them are quite tolerable and have mutual interests beyond cash flow and python. But both are far too smart to succumb to anything but knowledge sharing.
3. boys are girls are likely to be friends, before the onset of puberty. This strengthens the OP's argument, of course. I just find it fascinating that much of it appears to be entirely driven by the emergence of estrogen and testosterone and the physiological and emotional changes it begets. Powerful stuff, those hormones. I digress...
4. within the strict confines of socially accepted norms, men and women can "befriend" each other. But there are strict (unspoken) rules here. It's common to see married couples who enjoy each other's company (platonically) where one husband connects with the other's wife on some topic of interest and they develop mutually shared interests in talking to each other. That relationship is allowed, typically (in well adjusted marriages) to develop, so long as the "wife of one" and the "husband of the other" engage in their discussions in the presence of the other's married partner. So in this way, a friendship between a man and woman of pair-bonding age can occur, but with the over-watch of another. I find this societal framework interesting. It suggests that men and women can befriend each other despite being awash in testosterone and estrogen, but that there's still a societal recognition (and perhaps even self-recognition) that test and estro are formidable beasts that can't entirely be trusted.
