can i use a laptop charger with same input voltage but differen input amperage?

My original laptop charger is not working, can i use a new charger ? whose input 100-240v-2.4a (2.4a) 50-60hz and output 20v(20v)== 4.5a(4.5a). My original cahrger input 100-240v~1.7a 50-60hz and output 20v(20v) == 3.24a(3.24a).
