Got a chance to look over the fried capacitor you sent. Yes, the darkened condition is strong evidence of failure (shorted leading to overheating). This style of tantalum chip capacitor is almost vintage . . . very early package style that was replaced with a more robust configuration. Yes, it's a surface mounted part. That little pigtail is not the remnant of a lead-wire. I suspect that the replacement part was a more modern design but yeah, this was quite probably root cause of the radio failure. Bob . . .
