Lol no. When the Wiki compares the Namekian Dragon balls to the Earth Dragon balls it says.
"Once Porunga is summoned, he has the ability to grant three wishes, that are somewhat different in power to Shenron's wishes. For example, Porunga can grant the same wish more than once (e.g. revive the same person multiple times), unlike Shenron who can only perform the act once. Like Shenron, he cannot revive someone who has died of a natural cause (such as succumbing to illness) but is also limited to reviving only one person per wish whereas Shenron can revive an infinite number of people at a time. However, Porunga has no known time-limit for how long a person can be revived after dying unlike Shenron who can only bring back people who died within a year's time."
