Multihomed end sites usually get away with receiving only default route or some partial routes from their upstreams. So technically you can BGP multihome with Cisco 1600 or even smaller easily (dunno where BGP support is starting to become available).
Technically yes, practically no. At least not for the purposes people normally want to multihome.
I cannot confirm this observation from my experience supporting a number of customers with their multihoming setups that I've either designed myself or supported as part of "managed internet access" solutions. I _did_ see several badly designed setups though that had full tables (and associated hardware overkill) but didn't need it. Consequence: wasted money, worse convergence times and routers falling over because of RAM depletion and fragmentation over time.
