Some subset maybe, but once you add essential components such as security, no longer. When setting expectations here, it may be useful to reference RFC 7228 [1]. This identifies some clusters of devices (called classes here). The expectation is that full IoT functionality will be possible with class 1 devices (~ 10KiB RAM, ~ 100 KiB Flash). So, say, a Maple-class device (STM32F103CB: 128 KiB Flash, 20 KiB SRAM) is likely to support a fully secure IoT application when using constrained-class protocols. I'm citing Maple here because of its Arduino-like IDE and because breadboard-friendly development boards including USB and voltage regulator [2] can be had for USD $4 shipped.
