Yes. Actually you should neither without exceedingly careful testing. We ran with net.ipv4.tcp_tw_recycle enabled for a month, not realizing it was causing our site to be extremely slow for many visitors. See http://www.formilux.org/archives/haproxy/1008/3748.html for my list post about the problem. We might enable net.ipv4.tcp_tw_reuse later, which seems like a safer option, but for the moment we are looking at ways to improve, not jeopardize, stability. :-)
