Yes, but it won't clean up the code very much... Also, the 1st argument you're passing in is not an action, it's a route name...

For something like this, I'd probably create a macro or a partial to keep my template from becoming too hard to read.

Working with Laravel URLs

link_to_route

To get started, you can use link_to_route()...
link_to_route($name, $title = null, $parameters = array(), $attributes = array())

// routes.php
Route::get('/topics/{category}/{forum}', [
    'as'   => 'topics.show',
    'uses' => 'TopicsController@show'
]);

// *.blade.php
{{ link_to_route('topics.show', 'Link Text', [ 
    $topic->forum->category->id,
    $topic->forum->id,
    'page' => $topic->posts_paginated->getLastPage() 
 ]); }}

link_to_action

If you want to use an action, link_to_action() is very similar, except it uses the action instead.
link_to_action($action, $title = null, $parameters = array(), $attributes = array())

Given the same Route as above, you'd use...

// *.blade.php
{{ link_to_action('TopicsController@show', 'Link Text', [ 
    $topic->forum->category->id,
    $topic->forum->id,
    'page' => $topic->posts_paginated->getLastPage() 
 ]); }}

Result & Explanation

Both examples above will generate:
<a href="http://domain.tld/topics/23432/5434?page=2">Link Text</a>

Basically, anything after the expected number of parameters is exceeded, the remaining arguments are added as a query string.

Note

If you don't want to generate the HTML too, you can just use route() or action() respectively.

It's very simple. Generate the URL like you would with route parameters. Laravel will automatically append them as query strings.

Say your route looks like this:

Route::get('/{id}, array('as' => 'test.route', function($id){
    return $id;
}));

You would generate a link like this in your view:

<a href="{{ route('test.route', array('id' => 1,  'something' => 'here',  'another' => 'there')) }}">click here</a>

Your url would look like this:

http://localhost:8000/1?something=here&another=there
