you can use $root.$emit() and $root.$on()

const componentA = {
  template: `
    <button @click="callMethodInComponentB">
      call method in component-b
    </button>
  `,
  methods: {
    callMethodInComponentB() {
      this.$root.$emit('call-to-component-b', 2);
    }
  }
}

const componentB = {
  template: `
    <h1>Value: {{ value.toString() }}</h1>
  `,
  data(){
    return {
      value: 0
    }
  },
  methods: {
    plus(add) {
      this.value += add
    }
  },
  mounted() {
    this.$root.$on('call-to-component-b', add => {
       this.plus(add)
    });
  }
};


new Vue({
  el: '#app',
  components: {
    componentA,
    componentB
  }
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/vue/2.5.17/vue.js"></script>

<main id="app">
   <component-a></component-a>
   <component-b></component-b>
</main>
